I haven't seen these mentioned here. There are 18 Doodle Jump minifigures so far, available at TRU. There is a gray zombie, a green zombie, a Frankenstein's monster, and a werewolf in addition to a rapper, pirate, ninja etc. Pretty cool I think.
All of figures I have are the same as above except the rabbit is painted gray instead of yellow. I took pictures of my set
and posted them here:

Also, crossover figures with Spongebob, Batman, Sonic, and Spock may also be on the way.
