The Pump Chimera, also known as Mr. Pump, is a chimera encountered in Mother 3. It is one of the few chimera that assists Lucas rather than attacking him.


He is introduced by Dr. Andonuts when the party is looking for something to gain access Doria's Needle, along with Dryer Chimera and the Bucket Brothers. Ironically, he is Dr. Andonuts's least favorite of the three chimeras to choose from, despite being the only helpful one and the correct choice to empty the pool that hides the Needle.

One of the unused enemies in the game is named Pump Drago, insinuating that it may have been intended to be fought at some point.
