Black, black!
~ Kroodle shooting black magic to turn everything and everyone into Krockolors.

His assistant Krobloke reported to Kroodle to know that everything is being restored by Louie's crayons. He sends Krobloke to get Louie's crayons before he becomes turned into a chicken for failing.

Upon riding on the hot air balloon made by Louie, Kroodle appears in the form of thunderstorms and strikes down the hot air balloon, causing Louie, Yoko, and Blue Knight to fall into the forest.

Back again, Krobloke reports to Kroodle that Louie, Yoko, and Blue Knight were defeated by him, thinking that the trio won't be coming to rescue the Rainbow Fairy. Thinking that he won, it is false, because Louie, Yoko, and Blue Knight have survived the hot air balloon fall and flood in the grotto.

Upon entering Kroodle's Castle, Kroodle sends Krobloke to kill Yoko until Yoko foiled the pink crow. Later on, he shot Yoko with black magic and she turned into a Krockolor, alongside Blue Knight. Louie was able to defeat him by drawing a magic wand and giving it to the Rainbow Fairy. The Rainbow Fairy was able to restore all the colors and turn everything back to normal. Kroodle has turned into a good wizard. However, it is revealed he has turned into a clumsy wizard by using his wand upside-down by accident, turning himself into an evil wizard.
