Ickis, Oblina, and Krumm made an appearance on Rugrats season six, episode thirteen, "Ghost Story" (S06E13), both shows were created by Klasky and Csupo. This was the first time Nicktoons had a crossover, and it's success inspired others to follow suit.
Wow, instant sky flowers. Boy, are they noisy!
In one episode, a clone of Ickis graffitis a wall to read "The Gromble Eatz Fresh Produce" with the last "e" written backwards. However, when Ickis later has to clean the graffiti, the wall says "The Gromble Eatz Fresh Fruit."
During the opening credits, the Gromble says something different from every episode, one of his lines was "you make me sick". After the credits and the Nickelodeon logo is shown, a character from that episode says a line.
