Bee Mario

Bee Mario is a form Mario will take after collecting a Bee Mushroom, which is first found in the Honeyhive Galaxy, in Super Mario Galaxy and Super Mario Galaxy 2. When Mario takes this form his hat changes to better resemble a helmet with antennas and his overalls become yellow with stripes and he will grow a stinger and small wings, which allow Mario to take flight in a similar manner to a bee for a short time (however Mario sacrifices all of his jumping skills). Mario is also able to climb honeycombs and walk on flower petals and clouds. Mario will lose this form by taking damage or by touching water. By collecting coins in mid-flight, Bee Mario's fly gauge will slightly refill. If Luigi assumes this form his colors will be the exact opposite of Mario (to the point that even his shoes and hood will change to yellow). Also, his Spin radius will become smaller and the Spin itself will emit yellow colors, rather than the regular blue.

Bee Mario (and Bee Luigi) can be used in the Honeyhive Galaxy, the Gold Leaf Galaxy, the Sea Slide Galaxy, the Sand Spiral Galaxy, and the Honeyclimb Galaxy. This ability returns in Super Mario Galaxy 2, only usable in Honeybloom Galaxy, Honeyhop Galaxy and in the game's credits after collecting 120 stars.

Trivia

 * One contest on the Check Mii Out/Mii Contest Channel had players create Bee Mario.
 * When in Bee Mario Form, if Mario is placed behind an object, Mario's shadow seen isn't portrayed in his Bee Form.
