OUT OF CHARACTER
Backtagging: Yes, please! My timezone (GMT/UST) can make things difficult.
Threadjacking/threadhopping: As long as you're not butting into anything important or pre-planned. Use your own discretion.
Fourthwalling: Sure, I don't mind it.
ACTION
Fighting: Frog lives to fight. Yes!
Injuries: They happen and I'm for it happening, though Frog is a skilled healer. Anything permanent/serious wounds would have to be discussed first.
Telepathy/mind-reading: Sure! Feel free to ask, so you know what he's thinking aside from eating flies.
RELATIONS
Hugging: If you want to hug a slimy amphibian?
Flirting: ....But really, would you?
Kissing and/or other intimate actions: Again, WOULD YOU? XD Princesses need only apply.
