Count Von Sugar

Count Von Sugar is a one-time villain from the 2016 reboot of the Cartoon Network animated series, The Powerpuff Girls, only appearing in the episode "Checkin' Out". He is a fictional cereal mascot of an eponymous brand of cereal. Bubbles imagined him as a friend, who quickly turned into an enemy, in a fit of petty jealousy.

Biography
In "Checkin' Out", Bubbles went to the grocery store to buy some cereal. Blossom told her that she could only choose one cereal and it was very important that she chose the right one. While looking through all the options, Bubbles had a lot of trouble making the right decision. It also didn't help that the fate of the world rested in her hands, what with the Hungry Alien planning to destroy them if he didn't get his delicious dinner.

While pondering which cereal box to choose, Bubbles started imagining all of the cereal mascots coming to life. One of the cereal mascots was Count Von Sugar of the eponymous brand of cereal. Count Von Sugar flew out of the box and told Bubbles that if she was looking for a good box of cereal, she would need something with more "bite". Bubbles had lots of fun, making her decision, once she began partying with all of the cereal mascots and having a great time, making friends with them.

Eventually, after enough partying, Bubbles had to make a decision and it wasn't easy, given how much the other cereal mascots were pressuring her to do so. "Pick me! Pick me!", they all said, to no avail. Bubbles still couldn't make up her mind. "Choose all of us!" they offered, but Bubbles sadly told them that Blossom only allowed her to choose one. Every cereal mascot went right back to begging "Pick me! Pick me!"

Bubbles finally chose Cherry Chimpanzee, which angered every other mascot. In an awkward and instant shift of tone, every mascot turned on her and chastised her for not picking them. Count Chocula darkly and angrily insulted Cherry Chimpanzee, saying that he wasn't even made with real cherries of chimpanzees. He showed some real discern toward Bubbles for not choosing him.

Rainbow Raspberry, along with all the other cereal mascots cornered Bubbles and prepared to attack her but Cherry Chimpanzee showed Bubbles a hose, that sprayed out milk. Bubbles used the milk hose to blast all of the cereal mascots. Upon being squirted with milk, all of the cereal mascots melted to oblivion.

This was all happening in Bubbles' imagination, however. In real life, she just took a bunch of milk and started dumping it all over the cereal boxes, which led to her getting promptly kicked out, without any cereal at all.
