Bugaboom

Bugaboom is a boss that appears in Super Mario Galaxy and the sequel, Super Mario Galaxy 2. This boss is found in the Honeyhive Galaxy and is the leader of the Mandibug clan that infested the Honeyhive Kingdom.

Appearance
Bugaboom is a huge green Mandibug, with six legs and eyes that have a demented look to them. Unlike most Mandibugs, its body is flat instead of rounded. It will attempt to consume the player with its retractable mandibles, but after attacking it once, it will reveal its wings and fly rapidly around its planet and drop explosives from the underside of its body. Bugaboom can be best described as a beetle with one solid shell that's green and has a marking of a blast on the middle of the shell. Also, the mandibles look much like an ant's pincer.

Bugaboom's eyes look strangely hypnotic, meaning that it may not have been the one who planned the Mandibug attack and just may have been hypnotized into assaulting Mario. Of course, this may also mean that Bugaboom is simply demented.

Super Mario Galaxy
In Super Mario Galaxy, Bugaboom is fought on a planet with several dandelions and two Bee Mushrooms in the Honeyhive Galaxy and the level Big Bad Bugaboom. There is also a river of water to get rid of the Bee Mushroom. Under the planet a Black Hole can be found just in case Mario falls off. Once Mario arrives on the planet, Bugaboom drops from the sky and clicks its mandibles. It then proceeds to attack Mario just like a regular Mandibug would except it is much bigger. The only way to defeat him is by jumping, flying or using a dandelion stalk to get on to its back and then Ground Pounding.

Bugaboom will then take flight and fly around in circles so that Mario can no longer jump on its back. The only ways to get up now are to use Bee Mario or a dandelion stalk. Once on top of Bugaboom, a ground pound will finish it off. After that Bugaboom gets extremely mad and turns red. It will fly faster and once every pass it will turn on its side and fire bombs at the ground. It is impossible to hit Bugaboom while it is on its side so Mario must wait until it is going the right way and use a Bee Mushroom to hover above where it will be or aim with a dandelion stalk which is considerably harder as Bugaboom is moving so fast. Once Mario ground pounds Bugaboom a third time, it will explode and a Power Star will appear.

Super Mario Galaxy 2
Bugaboom makes its second appearance in Super Mario Galaxy 2 as a secret boss when Mario reaches the Puzzle Plank Galaxy. Its battle tactics are the same as in the previous game, but Mario must change his strategy: in lieu of the Bee Suit, Mario must become Cloud Mario in order to defeat Bugaboom.

Trivia

 * The name Bugaboom is a pun on the word Bug-a-boo, which is a term for monsters, generally minor children's book monsters.
 * Bugaboom shares its boss music with King Kaliente and Topmaniac. However, Bugaboom's boss music speeds up after it takes damage, which never happens with the King Kaliente and Topmaniac fights.
 * Bugaboom's boss music from Super Mario Galaxy returns in Super Mario Galaxy 2, where it plays the same way when Bugaboom is fought. It will also speed up again, like in the first game.
 * Bugaboom is the only boss from Super Mario Galaxy to appear again in Super Mario Galaxy 2, but not to be fought in Boss Blitz Galaxy.
