Games

Kirby Super Star

Biospark appears in only a few levels, and is quick to attack by throwing dozens of tiny knives (kunai). However, his attacks are all rather weak.

The Helper looks the same as the enemy version, and it and Kirby can use the same attacks.

Kirby Squeak Squad

After a long hiatus, Biospark returns with some new tricks. Now he'll hide behind a sheet of cloth that camouflages it into the background- except you see the outline and hands holding it up. Get close enough and Biospark will reveal itself and attack.
