I need some idea for a "grease monkey" cake for my grandfather's 90th birthday. He's very playful and loves animals and cars of all kinds so I thought this would be a great idea. I'm just not sure how to bring it all together. I thinking some kind of tiered cake since we'll have a fairly large crowd. Other than that, I'm kind of stumped.

what about a tool box with all kids of tools...I saw a cool peg board cake with tools on it too..I have a 3-D tool box in my pics if that helps...

If doing a sheet cake, there are a lot of cute pictures if you google "grease monkey" images.

For a tiered cake, it not' my expertise.

Bravo to him for being so active a 90 years old! This is a special birthday indeed.
