so kinda like the situation with Bloo and Mac your parents said you were to old for your imaginary freind now so you would have to get rid of them then your imaginary freind Wilt. Saw a ad on tv about this Fosters home for imaginary freinds any imaginary freind who needs a place to stay can go! So he showed you and now he gose there but when you realized you couldn't stay there they said you can still visit so ofc you do and now your well know around there and yk you have fun and hang out!
