Our aspiring scientist is excited to be entering this Peeps Diorama in the contest at school. It is "Dr. Peeps' Lab". She says that the one wall is colored blue so that the patient (in this case the green bunny Peep) can relax before undergoing surgery. Blue is a relaxing color.
The middle Peep is using a microscope to look at cells. The artist is particularly excited about cells, and will tell you all about them, if you give her half a chance.
The artist says that the third Peep is "working with chemicals, of course! How could he NOT be working with chemicals, since he has all those containers?!"
Artistically it may not win the top prize, but for a display of Peeps career goals, I think it is outstanding. Not that I'm biased in any way.
