Grobot

Grobot is a watering machine constructed by Brickle. When hit by one of the broken fountain parts, Grobot goes haywire and attacks Brickle upon sight in the Maintenance Hut of Mushrise Park, Mario and Luigi engaging battle with it to shut it down.

Appearance
Grobot is a blue robot with a ball-shaped body and metallic arms normally used to pour water out of, tipped with yellow lining. It has a mouth-like hole that water comes out of rimmed with yellow. has red eyes, but had blue eyes prior to going haywire, and a two-feathered top like the fountains in the park.

History
Grobot first appears once Mario and Luigi rescue Brickle from the park's main fountain in a cut-scene showing one of the larger fountain parts landing on it while it's watering the plants in the Maintenance Hut, and causing it to go haywire. Soon after, Mario and Luigi follow Brickle to the hut to find he was quickly attacked by Grobot and hurled across the hut area. It then attacks Mario and Luigi. After the battle, Grobot is destroyed, and not seen for the rest of the game.

Battle
Grobot attacks by blowing up balls of water on its mouth and shooting them at Mario and Luigi, who must jump over the small balls of water, and either perform a timely jump on to the big ball of water or idle as it bounces over their heads. Grobot may also chase Mario and Luigi through the foreground, shooting balls of water at them which the Bros. must jump over before it hits them. If at least one brother is remaining, Grobot will eventually run into a rock and cause self-damage.

Grobot is also fought in the Battle Ring, as Grobot X. This version has a red body and blue eyes instead, and the water balls Grobot shoots are now also red.
