It was hosted by guest star Ron Pearson, and created by William Hanna and Joseph Barbera.
The show was executive produced by Hanna and Barbera, along with Jay Wolpert for the autumn season being aired for eight months.
Six groups of two teams of four children (always the "Sludge Puppies" in red and the "Drainiacs" in yellow) each competed in a game similar to "Hot Potato" to answer questions and win prizes.
As soon as the number of passes equalled the team's guess, the player with the object ran to the middle of the studio and honked a bicycle horn.
If they were wrong, ran out of time, or threw the object out of bounds during play, they received nothing; in addition, the chosen dinosaur spun a "wheel of torture", which caused that team to get slimed with some by-product poured into the sewer (for example, the "ice cream parlor" would cover the contestants in melted ice cream).
