Goompa

Goompa is Goombario's grandfather. Now old and with a bad back, Goompa used to travel the world with Koopa Koot and Bootler, he learned many things on his travels about the world. He passed this knowledge onto Goombario. He is married to Gooma. He first appears repairing the veranda round the back of the Goomba house with a hammer. However, the veranda breaks, and when Mario comes to get the hammer, Mario finds the veranda has fallen down the cliff, and falls down as well. When Mario finds the hammer in the forest below, Goompa "joins" his party, and tells Mario how to fight and to use the battle system in the fight against Jr. Troopa. When they get back to the village, Goompa recommends Goombario joins Mario.

Trivia

 * Goompa is a portmanteau of "Goomba" and "grandpa", which he points out upon meeting Mario. In fact, Goompa may just be a general name for all Goomba grandfathers.
 * It is possible he has a severe hatred of Shy Guys, as the anonymous tape Koopa Koot asks Mario to retrieve from Goompa is not named and seems to be a dark secret. However, Koopa Koot exclaims "Suffering Shy Guys!" on retrieving the tape, which may be the name or a random exclamation.
 * It is strongly hinted he trained the Master.
