|This greedy little mouse managed to infiltrate HitGrab HQ by disguising himself as one of the developers. Capturing this mouse will return the stolen code to HitGrab, and you'll be rewarded with a special HitGrab gift!|
Birthday mice were released on 5 March 2009 as a precursor to MouseHunt's 1st Birthday on 7 March 2009.
- Birthday mice look similar to Elf mice, but with a birthday hat and a birthday cake next to it.
- Due to a glitch, Birthday mice could be caught in the Meditation Room when they were first released. This was fixed shortly afterwards.
