Uhhh bold means guaranteed
4 new costumes (One for Hyehehe, possibly one for Epic Whaddle. One of those two is gonna be a blue and yellow swimsuit. This is out there but please one for Rare Hoola)
Young Hoola for SummerSong Junior
New DoF SummerSong costumes (Maybe one for Tuskski? Idk it has potential. One for Pango, Barrb, and Dandidoo. Pummel could get a swimmer costume, referencing the classic shark fin prank (unless Hyehehe steals that idea). Clamble could be beach-themed, like with a clam head and stuff.
Decorated Earth Lands/obstacles
Gnarls in DoF (on Cave Island)
Rare Wubbox on Wublin Island (Halfway through or at the end of SummerSong)
Epic Arackulele, based around slime n ooze and stuff like that
New class (NOT island. Cause like we've gotten 2 islands in less than a year why would we get 3? It'd be more interesting to get an entire new class that DOESNT have its own island imo)
Rare Drummidary. Unlikely but I'm holding out hopes. My prediction for it is a more pirate-themed teal Drummidary. I drew it but it's saved on another device so uh
Fire Oasis remix.
