My thoughts are that House of Mouse will have an All-Star crossover with some Disney Channel shows (past & current), streaming on Disney+🤔

My thoughts are...

1. House of Mouse × Kim Possible, American Dragon: Jake Long, Wander Over Yonder and Hamster & Gretel

2. House of Mouse × Gravity Falls, Amphibia, The Owl House and Hailey's On It!

3. House of Mouse × The Buzz on Maggie, Fish Hooks, Kiff and Big City Greens

The text of these choices are in initials, so...

KP=Kim Possible

ADJL=American Dragon: Jake Long

WOY=Wander Over Yonder

GF=Gravity Falls

OH=Owl House

HOI=Hailey's On It!

TBOM=The Buzz On Maggie

FH=Fish Hooks

BCG=Big City Greens

Disney will let us know which!

All of them including the original disney era characters

Moon Girl and Devil Dinosaur! Amphibia! The Owl House! Pepper Ann! Ducktales! Gravity Falls! Kim Possible! Lilo & Stitch the series! Big Hero 6 the series! Recess! American Dragon: Jake Long! The Proud Family (both series)! Milo Murphy's Law!

Personally thinks Loud House and Gravity Falls.
