What's under your bed?

We just got home yesterday after work and Brandon went to his room to look for a particular toy.  I was straightening up a little and Olivia was on the floor playing.  All of a sudden, I hear "MOMMY!  Come and Help me, I'm stuck!"  "MOOOMMMMMYYYY!"

Thinking something was horribly wrong I go running into his room, Olivia hobbling close behind me.  I go into the room and this is what I see...

Naturally I did what most mothers would do at this point...I laughed until I almost peed my pants!  I could even hear Brandon's muffled laughs from under the mattress because he knew how silly he had to look.  I said don't move I'm getting my camera, and he just said "okay, I'll wait here."  Like he could go anywhere if he wanted to...hahahaha.
