Any young boy raised on Calvin and Hobbes has dreamed of retreating to a tree fort to hurl snowballs and Susie Derkins and host G.R.O.S.S. (Get Rid Of Slimy girlS) meetings. One amazing dad created a nursery for his kid that would be any Calvin & Hobbes fan’s dream come true. The room includes a big Calvin & Hobbes-themed mural, and a treehouse bed with both a ladder and a slide. Just looking at it makes us want to turn back the clock to be a kid again.
