My grandsons birthdays are 4 days apart so this was a joint cake (2 years old and 4 years old). They both love Batman; however, the 4 year old really wanted a Zhu-Zhu pet party (he calls them evil chipmunks) and the 2 year old loves Muno from Yo-Gabba-Gabba. After much convincing, my daughter got them to agree on Batman. I surprised them by throwing in a little of all 3 (the Zhu-Zhu pet is the little thing by Batman).
