Penguru

Penguru is an elderly penguin in the game Super Mario Galaxy and Super Mario Galaxy 2. He appears in the Sea Slide Galaxy, the Bigmouth Galaxy, and the Drip Drop Galaxy. He holds one of the five Silver Stars in the Sea Slide Galaxy. He often goes to the Bigmouth Galaxy to relax and think. He also appears with a group of other Penguins (of whom he is apparently the grandfather) on an island in the Drip Drop Galaxy, distressed about the outbreak of Gringills (referred to as 'Giant Eels' in the level name). He lives on a floating island in the center of the Sea Slide Galaxy along with various enemies. Penguru appears for the last time in the Grand Finale Galaxy, gazing at Princess Peach's Castle (which he is apparently familiar with, despite not being a resident of Mushroom World). He is a tall penguin, similar to Coach, with a long grey beard, and is pictured with a flipper on his chin, looking out into the sky.

In Super Mario Galaxy 2, Penguru appears in two galaxies, which are the Hightail Falls Galaxy and the Cosmic Cove Galaxy.

Penguru's Island
Penguru lives on an egg-shaped island (similar to a Yoshi Egg) that is suspended in the center of the water 'ring' that is the Sea Slide Galaxy. The top half is covered with sand, and patches of grass, whilst the bottom half is covered with shallow water. Penguru stands at the top of the island, which is flat, and covered in grass. The only way to reach the island is through a jet of water, that comes from a platform on the sea slide, after a valve has been spun down.
