Aw dude get out of the hot tub that is nasty
EDIT: More correct guesses have come in! June is indeed Bayonetta and Gus is the goblin from Homestar Runner! Hannah is Yoko from TTGL and Cyril is Brian from Quest 64. That leaves Aley and Maxx!
EDIT 2: I missed that UltimaRCR correctly guessed that Aley is Igniculus from Child of Light! That means that Maxx and Sophia are the last ones standing. Good luck!
