Tip Network

The Tip Networks are a new type of object in Super Mario Galaxy 2. Tip Networks are mounted on a green and yellow signboard-like post. They provide helpful tips for the player for upcoming obstacles or challenges that lie ahead. Mario will need to stand in front of the Tip Network to activate it. The TV will show a quick demonstration of how to surpass a difficult part of the galaxy. Unlike the Cosmic Spirit, it will not degrade the Power Star to a Bronze Star. The Tip Networks play a similar role to Princess Peach's Castle in New Super Mario Bros. Wii, except that it does not cost the player anything.

Trivia
After the Tip Network finishes showing the player how to overcome obstacles, the entire level is reset to the way it was with all of the enemies returned as if they haven't been defeated yet even when the player already has. Plus, the Star Bits and Coins come back as well. It is shown that the player can obtain 999 gold coins and 999 star bits as demonstrated in Fluffy Bluff Galaxy.
