| “ | Even though its official species name is recognized to be 'Pentumbra' (because of its five limbs and the shadow it casts), everyone just wants to call this Monster a 'Shady Long-Legs'. The Ethereal Quad's affinity for the Shadow Element causes an unusual sticky pink residue to form on its legs - something to do with the fact that they're so often bathed in darkness. Apparently this phenomenon has been known to happen at large scale, when the dark matter of the Rift between dimensions seeps out from interdimensional fractures. It could be a trick of light, but the gloom that dwells beneath a Pentumbra almost seems to take a life of its own... but because it's nothing more than a shadow of a shade, it tends to imitate other beings' sounds rather than create its own. | ” |

Description[]
Pentumbra is a Quad-Element Ethereal Monster that is found on Ethereal Workshop and Shadow Islet. It was added alongside X'rt, Rare Pluckbill, and Epic Viveine on April 17th, 2024 during version 4.2.1. As a Quad-Element Ethereal on Ethereal Workshop, it is obtained by successfully extracting the energies of a Plasma Meeb, a Shadow Meeb, a Crystal Meeb, and a Poison Meeb, using the Super Hyper-Refined Synthesizer by spending 5,000
. Its successful Synthesis time is 1 day and 18 hours long. As a Quad-Element Ethereal, Pentumbra has a decent Shard production. The Goal for placing your first Pentumbra rewards the player with 200
.
Pentumbra can be teleported to Shadow Islet once fed to level 14 or obtained by Dish-Harmonizing a Monster using the Dish-Harmonizer. Its incubation time is 1 day and 16 hours long. As a Quad-Element Ethereal Monster, Pentumbra has a great Shard production compared to other Monsters on Shadow Islet.
Song[]
Old Sound (Memory; Ethereal Workshop):
Current Sound (Ethereal Workshop):
Filter (Shadow Islet):
Voice actor: Dylan Cole[1]
Instruments: Filtered Vocal with samples of other Monsters
On Ethereal Workshop, Pentumbra's contribution to the song is a low, somewhat raspy “laa,” similar to Tweedle. Multiple of these voices can be heard on top of each other, and they’re usually short laa's that make some sort of melody. For Pentumbra's first track, Jeeode's sound can be heard singing in the same rhythm as Vhenshun's clanging. For Pentumbra's second track, the end of Yooreek's first track can be heard towards the end of it. For its third track, Jeeode's Ethereal Island sound is heard alongside the laa's, as it mimics the melody a bit.
The first track mimics and plays with Vhenshun, the second track overlaps and mimics and harmonizes with Yooreek, and the third track plays in the Auglur verse, then again in the last verse.
The filter is noticeable in its third track on Ethereal Workshop and its third track on Shadow Islet, sounding like an ominous drone.
VSTs[]
- Main article: VSTs
Virtual Studio Technology (VST) is a plugin format that allows audio software to integrate with digital audio workstations (DAWs). VST plugins come in two main forms: instruments (VSTi), which generate sounds, such as synthesizers and sample libraries, and effects, which process audio, through tools like reverb or distortion. Individual sounds within these plugins may be referred to as patches, presets, samples, or articulations, depending on the plugin. The Monster-Handlers utilize several VST plugins to create the sounds of instrumental and sometimes vocal Monsters. Note that many pages incorrectly label patches as "SoundFonts", an unrelated audio format.

Synthesizing[]
Pentumbra is only available for purchase or synthesizing on Ethereal Workshop. As a Quad-Element Ethereal, it requires a pre-existing Triple-Element Ethereal to "build upon". Pentumbra, being a Quad-Element Ethereal, requires two Meebs attuned to each of the Triple-Element Ethereal's Elements, and three Meebs attuned to the fourth Element in the Super-Hyper-Refined Synthesizer. The following Triple-Elementals can be used to synthesize Pentumbra:
![]() Meebkin |
+ | ![]() ![]() ![]() 2 of each attuned Meebs of Meebkin's elements |
+ | ![]() 3 Poison Meebs |
![]() Blarret |
+ | ![]() ![]() ![]() 2 of each attuned Meebs of Blarret's elements |
+ | ![]() 3 Crystal Meebs |
![]() Flasque |
+ | ![]() ![]() ![]() 2 of each attuned Meebs of Flasque's elements |
+ | ![]() 3 Shadow Meebs |
![]() X'rt |
+ | ![]() ![]() ![]() 2 of each attuned Meebs of X'rt's elements |
+ | ![]() 3 Plasma Meebs |
- There is no indication that Synthesis chances are affected by what combination is used. Of the four Triple-Element Monsters you can use, Meebkin is the easiest to obtain, as it is the most stable out of the four combinations.
Note that the successful synthesis of Pentumbra will result in the Triple-Element Ethereal Monster being lost in the process.

Likes[]
Every Monster has different things that they like. For every unique object that they like that's placed near the Monster, the Monster's happiness will increase by 25%. Placing more than one of the same liked item near a Monster won't increase its happiness by an additional amount. If there's a Unity Tree or a Primordial Monster of the same rarity on the Island, items don't need to be near the Monster. Below are the things liked by Pentumbra:

Earning Rate and Maximum Income[]
Earning rate is in Shards per hour and depends on Happiness % (Likes increase Happiness) and Monster Level. Each Monster also has a maximum amount of income it can hold at a time. Increasing the Monster's level also increases this limit.
Feeding Monsters[]
Each Monster needs to be fed four times before it reaches the next level. Increasing the Monster's level increases the shards earned per minute, as well as the maximum shards earned.

Notes[]
- Pentumbra represents the Shadow Element, just like Loodvigg, the Celestial that shares it.
- Pentumbra's name is a portmanteau of "penta" (meaning 5, referring to its 5 limbs) and “umbra” (a part of a shadow).
- It could also be a reference to “penumbra”, another part of a shadow; however while it sounds more similar to the monster’s name, it’s more than likely the umbra is the one that contributes to its name, as an umbra is the darkest part of a shadow (which is what sings beneath Pentumbra) whilst a penumbra is the partially shaded outer region of a shadow.
- Pentumbra may be based off of an eclipse, due to it utilizing a light, blocked by its body, to create its singing shadow.
- Yooreek and Jeeode can both be heard overlayed onto Pentumbra's second, first, and third tracks respectively.
- Pentumbra is one of the first Monsters to reference a community-made meme. One of its nicknames, "Akhuhoth", is a reference to a fan-made Monster of the same name that became a meme in the community.
- The phrase "Shady Long-Legs" likely references the order of arachnids whose members are often known as daddy long-legs (harvestmen).
- This phrase was also used by Monster-Handler Jenn in the Echoes of Eco 2024 trailer.
- Pentumbra's sounds were changed after its release to make its voice sound more noticeable, but its memory game sound still uses the old one.
