Hexagons are the Pairo's shape so I think it's that

I dunno why it's so early though

My first thought is that it was the coloss-eye for ethereal island but that doesnt look like the ethereal island backdrop so i have no clue

It's a HEXAGON

Hexagons are paironormal.

nvm its paironomal island

Maybe a Titansoul because the effects.

Epic Cataliszt/j

It might be a critter for paironormal island

Something that isn't noteworthy enough to be the centre piece of the 13th Anniversary Monument, it seems.

THE HEX!
