An idea created between gemeni6399 and myself....it's Pouch Punk!
Unlike other monsters, this plush roo is just a kid, but that doesn't mean he's not dangerous! A bouncy brat at heart, Pouch Punk just wants to do what he pleases, playing practical jokes and using his boxing gloves to knock around anyone who tries to stop him.
When he encounters someone who tries to scold the young roo, Pouch Punk just laughs and bops their tummy with his glove, making a little slit appear. The roo then jumps right in, giving the victim a pouch that Pouch Punk sinks into to get cozy. The new sudden feelings overwhelm the victim, the pink ranger in this case, filling them with happy thoughts and motherly desires.
The longer Pouch Punk is inside, the more these emotions take over until they just want to keep the cute lil roo all safe and snug in their pouch! They don't notice their body starting to change, swelling into round soft kangaroo features as they grow to accommodate their new passenger. Before long they start to see themselves as Pouch Punk's momma, wanting only to love and dote and encourage his bad behavior (they think he's just being cute!)
Soon the transformation completes and the pink ranger has become a full-fledged plush momma roo, who would do anything to protect her special joey from harm.
Pouch Punk gets stronger the more people he corrupts into enabling momma kangas...here he's enjoying having absorbed the pink ranger's powers, giving himself a new ranger outfit so he can 'play' with the rest of the rangers.
