I know we shouldn be thinking about characters too much but I just drew some ideas for Background or very minor characters that roam around camp or something.
(Left to right) the first kid is Bobby, he like medieval junk. Then his best friend Kyle, he likes jellyfish a lot for some reason. Then Ann, she's half duck. Then Jenna, she's a tree person thing.
And I had these other two characters that I was too lazy to draw ;) Cameron, he's a knight. And John, this really nerdy guy with an apple for a head.
So these are just ideas ^3^ hope u like
Note: just noticed Bobby and Kyle are ALOT like Spongebob and Patrick.
