Dromba

Drombas are Grombas found in Dreamy Pi'illo Castle in Mario & Luigi: Dream Team. Their name comes from a combination of the words "dream" and "Gromba". Drombas are weaker than Grombas because they appear in clusters, which attack by forming an L-shape line and then rolling towards Mario. If there are not many Drombas left, they just roll towards Mario one by one.
