Master Green

Master Green is a mid-boss in Kirby's Dream Land 2, his sole appearance in the Kirby franchise. Defeating him yields the Spark ability when inhaled and swallowed.

Physical appearance
Master Green is a large sea jelly who wields electricity. His head is dome-shaped with two small black eyes, and holds up 8 tentacles. Oddly enough, his artwork from Kirby's Dream Land 2 is depicted as orange-yellow instead of green. This was later fixed in the Kirby of the Stars Pilot anime.

Kirby's Dream Land 2
In this game, Kirby will encounter Master Green at some point. Master Green's attacks range from throwing lightning-rod shock waves at Kirby, to skidding around, throwing shock stars that explode (which Kirby can inhale and shoot back at him), and producing shock waves from his body (similar to Sparky's attack plan). Defeating him rewards Kirby with the Spark ability.
