If Pinball Kirby hits Nimbus three times, it will start to rain and the Big Kirby will open his umbrella.”
— Kirby's Pinball Land instruction manual
Nimbus (Shower in Japan) is a white cloud enemy (not to be confused with Loud). Originally, Nimbus appeared as one of Paint Roller's drawings. When it is drawn, it comes off the canvas and starts shooting down small, yellow bolts of lightning before flying off-screen. It later appeared as an enemy in Kirby's Pinball Land and fodder summoned by Wiz in Kirby & the Amazing Mirror. In both of these appearances, Nimbus appeared as a real enemy instead of a drawing.
Nimbus is named after the cloud of its same name, which is a precipitation cloud and casts thunder bolts like the enemy.
