Hmm, for most people I see them do something called Kai-June. Basically a Kaiju theme for the month. But it's relatively similar to Macro March, which is something you've already done Xp

Yeah sadly, which is why I'm still looking around for ideas.

Ooh! I can think of a few potential themes that’d align with June;

-Gelatinous/Jelly-filled June! An underrated expansion substance~ Get yourself all heavy and ultra-jiggly-wobbly! Could even be entirely gelatinous, like living jello or slime!
-Jumpin’ June! Kangaroo and roo-adjacent forms, plump and pear shaped~!
-Jester June! Brightly colored clown or jester gear, fulla jingly bells and embarrassing attire!
-Junk June! Extra large “Junk,” whether it be rear ends (padded or otherwise) or of the more *lewd* variety of “junk~”
-Jive June! Tie-dye hippie aesthetics~

And of course;
June’s pride month, so there’s always that~!

For more June-related topics-
Could do “summer break” or “early summer!”
Heading down to the beach or hitting up the local pool~
Dive suits or pool toys respectively possible~

Or, “summer swelter!” Doing stuff to beat the heat, be it filling up with cold water, gorging on ice cream/popsicles, or being blown around by a fan!

Um... Summer themed. Make Chris a sand castle creature maybe. Or a pool toy. Or like, a cold drink creature.

Make Chris look like one of Mario Kart's Rainbow Roads for Pride I guess.

Uh, I think stink bugs are also called June bugs?
