Always the vain one, Pudding is never one to back down from a challenge unless she has been humiliated to an extent. Her competitive attitude and jealousy towards Ulala is mostly likely caused by her sometimes childish personality, and her natural competitive side from her days as a teen idol. Pudding also has quite the temper when she doesn't get her way. This usually goes hand-in-hand with her being humiliated such as in Part 2's second report when she shouts "I quit!" after being beaten by Ulala.

Despite this, Pudding seems to have respect to those who are better then her; she treats Ulala nicer in Part 2 when issuing a challenge to her unlike in the first game. However, she still likes to butt in on other's shows in both games, and doesn't hesitate to gloat when she is performing well.
