Voiced By Tom Kenny

Peepers is a grumpy imaginary dog as well as the one in charge of all of the happiness in Koosland. He is voiced by Tom Kenny.



Peepers was Dee Dee's first imaginary creation and the creator and guardian of Koosland, thus being left responsible for the well-being of the entire land. It is told that he gave away so much happiness for all the creatures in Koosland that there was no more left for himself. At some point, Koosy was appointed as his guardian and protector.

Jeepers, Creepers, Where Is Peepers?[]


Peepers in his dragon form.

One day in Koosland, a mysterious alien known as Hookocho appeared seeking to destroy Koosland for unknown reasons and steal Peepers' powers for himself for his evil plans of conquest. Hookocho then abducts Peepers and begins draining his powers on his ship, causing the poor being to painfully mutate. To save him, Koosy sought the aid of Dexter in hopes of using the Robo-Dexo 2000 to stop the alien warlord. The two eventually join forces and confront Hookocho, but the evil alien proves to powerful for them. Just as things seem bleak, Peepers suddenly mutates into a giant dragon and squashes Hookocho while green shards fly away, bringing peace to Koosland once more. In the end, it even seems as though Peepers has regained some of his lost happiness.
