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 the Puzzle Plank 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 the Ground Pound symbol emblazoned on it. Also, the mandibles look much like an ant's pincers.

Super Mario Galaxy
In Super Mario Galaxy, Bugaboom is fought on a planet with several Fling Flowers and two Bee Mushrooms in the Honeyhive Galaxy and the level Big Bad Bugaboom. There is also a river of water that will deactivate the Bee Suit if touched by Mario. Under the planet is a Black Hole. . Once Mario arrives on the planet, Bugaboom drops from the sky and clicks its mandibles. It then proceeds to attack Mario. The only way to defeat him is by jumping, flying or using a Fling Flower 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 Fling Flower. Once on top of Bugaboom, a ground pound will make it get extremely mad and turn 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 Fling Flower 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.
 * This boss, along with Fire Gobblegut, are the only bosses in Super Mario Galaxy 2 that can only be accessed by a secret star mission.
 * Bugaboom can be hit when he is flying without a Bee Mushroom or a Cloud Flower by triple jumping towards him and then performing a ground pound on his back.
 * Glamdozer's boss battle music seems to be a remix of Bugaboom's boss battle music.
 * He has some obscure similarities to Wiggler in that they are both insects and their music is used for other bosses, but speeds up with each hit, which is unseen in other bosses that share their themes.
 * In the Prima guide to "Super Mario Galaxy 2", one of the pictures for Bugaboom's article was a picture for King Lakitu's article instead.
