Quick note: I think people should be allowed to enjoy things and if you like a series or book considered childish then who cares, it makes you happy, that's what matters

That being said
Here's this

Florida likes a lot of stuff that's considered childish and is p self conscious about it

Occasionally he'll make a comment about it around other people to see the reactions

He keeps it to himself bc he doesn't want his partners to think any less of him

But he's got so much stuff in his other apartments

Blues clues books

Max and ruby books

He watches yo gabba gabba

He's got an alligator onesie

So many stuffed animals

Disney cups

Silly straws too

That's all I got :P
