I am spending my 20 credits from the Christmas Gift on the penguin name, who's name is "Slappy". Don't ask me why. Some fiesty penguin. Check the description, you'll see his name.
A glitch: Go to the area in the cave by the water. The first area, where the rocky ledge is. The one that the tip has a puddle. Slowly slide down it, and when in the water, the glitch appears.
