Rare Grumpyre

"How does this Monster remain airborne with so many holes in its wings? Are those perforations the result of repeated run-ins with its own head spikes? Many questions swirl about this volitant being and the Rare Grumpyre finds it all very amusing. Or does it? Like the common variety, this monster's mood is difficult to interpret given its furrowed brow and fierce snarl. Oh, well Shadow is as Shadow does."

Description
The rare Grumpyre, as opposed to its "common" counterpart, has green eyes instead of red, is covered in spikes, and has another pair of wings instead of arms. It also has nine teeth rather than two teeth and appears more menacing.

Song
Audio Sample:

Just like its Common counterpart, it sings "Boom shikala shika,Boom shikala shika," on Cold Island, and "Boom shika la, Boom shika la la la la Boom shika la, Boom shika la la la la" on Ethereal Island.

Breeding
Like all other Rares, Rare Grumpyre is only available for breeding during short time periods announced in the game.

Breading on Cold Island
The Rare Grumpyre can be bred using a combination of a Deedge and one three-element monster. Possible combination(s):
 * Deedge.png + Congle.png Deedge and Congle
 * Deedge.png + Bowgart.png Deedge and Bowgart
 * Deedge.png + Spunge.png Deedge and Spunge
 * Deedge.png + Thumpies.png Deedge and Thumpies

Breading on Ethereal Island
On Ethereal Island, breeding a Grumpyre with any other monster can result in a Rare Grumpyre instead of regular Grumpyre. A two-element Ethereal is a more likely outcome than the Rare Grumpyre. Once a Rare Grumpyre is available, breeding it with a regular Grumpyre to get more Rare Grumpyres will avoid getting two element Ethereals in the way.

Earning Rate and Maximum Income
Earning rate is in coins or shards per hour and depends on Happiness % (Likes increase Happiness), also each monster has a limit to how much income it can hold at a time. Increasing the monster's level increases the limit.
