(Seeing as to how it’s very likely that the Magical seasonals are going to Nexus)
Almost every seasonal goes to at least 3 islands. (Not counting Collisingum)
Punkleton- Plant, Gold, Shanty
Yool- Cold, Gold, Shanty
Schmoochle- Air, Gold, Shanty
Blabbit- Water, Gold, Shanty
Hoola- Earth, Gold, Shanty, Air
GobbleyGourd- Haven, Oasis, Shanty
Whizbang- Light, Nexus, Shanty
Booqurm- psychic, Nexus, Shanty
Ffyddll- Faerie, Nexus, Shanty
Clavavera- Bone, Nexus, Shanty
Monculus- Wublin, Ethereal, Shanty
Viviene- Shugabush, Amber, Shanty
The only ones left out of this pattern are
Spurrit, Carillong, And Jamboree.
And this^ is fine and here’s why:
-who cares about Spurrit
-Jamboree already goes to all of its possible islands
-Carillong is already on Nexus in a way.
(Plinkajou and Carillong share the EXACT same instrument)
