For me, these croissants look like phineas from Phineas and Ferb, Disney characters. I just filled up the croissants with ham and cheese, then cut them into two. I put these eyes food picks (affiliate-link below) to make them "alive". Very simple yet cute indeed!
Details for each box :
1. "Phineas" ham & cheese croissant
2. Pizza flavoured Turtle Bun
3. Corn on the cob
4. Pork dumpling
5. Carrot sticks
6. Banana for recess
My kids love the written banana. Just score the banana peel with sharp knife, and it will turn brownish in few minutes.
