Zsa Zsa Labrador is a spoof of glamorous actress, Zsa Zsa Gabor.
By air date, this is the series finale.
The penguins used by Professor Nimnul in the previous episode appear in this one as well, this time as backup dancers for Canina La Fur while she shoots her commercial.
Zsa Zsa Labrador does not appear to actually be a Labrador breed of dog.
This marks the last of two consecutive episodes in which Canina La Fur appears as a client to the Rescue Rangers. She is the only client to use their services twice and also happens to be their final client.
