Balloonification can occur any time in any circumstance. This Tropical Kangaroo here blinked but lucky for him, he didn't "miss it" as they say. No longer shall this island adventurer need raft or boat for he is balloon now with freedom to flutter and float. All complementary courtesy of a demon prince goat.

I'm not sure if the author Tropical Creatures/Kiro has an FA page or elsewhere to link to so please, send me a note if you know their information. Gotta give props where props are much due!

Disclaimer: Gumroad Tropical Kangaroo does not come with inflation. The bloating shapes and animation was done by me.
