Flamster

''"...This rodent Pettomon is ridiculously annoying to any opponent. It can shoot seeking bullets, making it very hard for the enemies to dodge..." - in-game description''Flamster is a Fire type Pettomon that shoots homing shurikens. It resembles a flying squirrel.

Flamster's good fire-rate, coupled with fair damage and the homing ability makes it a good placeholder for Volcanis or Quokkaroo.
