What's that lemon doing in my bed?

So I got this new bedding that I picked out with my favorite guys - Spiderman, Hulk, and Captain America and who steals my thunder? Sud Z Lemon!!! I can remember not too long ago he was around in all my pictures (my crib!) and now he is in my big boy bed!

I have to say he does look good with his yellow coloring and all, but just to let you know, my favorite color is RED!
