Thunderdance is a theatrical show consisting of Irish music and dance. A TV advertisement shown in "D.W., Dancing Queen" describes it as an "Irish step-dancing extravaganza." D.W. and Binky watch the advertisement and get the idea to do a dance presentation for their project. Thunderdance is mentioned again in "Kiss and Tell" by D.W.
The advertisement mentions the following acts:
- O’Kelly and the Weasel: a rat in a green suit and a woman (not a weasel) in a weasel costume
- The Great Big Potato: a person dressed up as a potato
- The Queen of the Mist: a monkey with long brown hair in a green dress
- The Prince of the Dance: a bare-chested blond aardvark in a white vest
