Trivia: In the previous episode on the wall of the Goodies' office was some graffiti reading "it's gibbon time". In this episode the graffiti now says "it is still gibbon time".

Kitten Kong - S2-E7
Trivia: On many recent specials and Live-shows, Tim has mentioned that in the scene where the Cat is dragging him face-down along the ground in the park a dog came out of nowhere and laid some do-do in his path. Since Tim didn't want to ruin the scene, he decided to continuously move himself right over it. Clearly it's something he hasn't forgotten.

Kitten Kong - S2-E7
Trivia: When Tim is being dragged along by the cat a bit of a brown something appears. He said in an interview that this was a long stop motion sequence. During filming a small dog ran through the shot and relieved itself right in his way. Because being stop motion it would have taken too long to re-shoot the scene, Tim volunteered to be dragged into and smeared over the mess, for the sketch.
