Who lives in a pineapple under the sea? Porus and spongy and yellow is he!
I use Oogoo for casting sponge bob and you can find the recipient here: http://www.instructables.com/id/How-To-Make-Your-Own-Sugru-Substitute/ Oogoo sets in less than 10 minutes so printing molds is a great way to build an army fast :). Add a few drops of essential oil to the mix and after a few days your object will smell like that instead of vinegar. Have fun.
