Dromba

Drombas are the Dream World version of Grombas that appear in Mario & Luigi: Dream Team. Their name comes from a combination of the words "dream" and "Gromba". Drombas appear in clusters of ten to fifteen, and attack by forming a column with an extended row, making an "L" or "T" shape, and then rolling towards Mario, who can move to position his jump. If Mario jumps while lined up with the long row, he bounces across several Drombas. If there aren't many remaining Drombas, they will instead roll towards Mario one by one, which is dodged by jumping over or on them.
