Penny the penguin is an underwater expert who impresses everyone with her brain power and her super-fast belly slides. She may be the smallest cadet, but she has no trouble keeping up and often arrives just in time to save the day.

She loves 'flying' underwater, building up her collection of fish photos and cooling off after a good day of training in a bath full of ice cubes.

She likes ice baths, eating kelp-icers and swimming, She dislikes being woken up by Rod

Her quote is "So cool"
