Waaa!!! Was a ten minute-long children's gameshow that airs on S4C during the holiday period.
It is presented by Tudur Owen and S4C presenter Mari Lovgreen. Neither appear in the programme, only providing voice-overs.
During the course of the competition, contestants are seated in a chair that moves along rails above four tanks containing either foam or gunge. The tanks are filled with foam, green gunge, foam, and red gunge consecutively. The fifth tank contains multi-coloured balls. While sitting in the chair, the contestants are asked questions. For every question they answer correctly, their chair moves along to the next tank. However, if the contestants answer a question incorrectly or do not know the answer, they will be thrown into the foam or gunge tank below them if in the gunge a clown will chuck buckets of gunge on them. If they are successful in answering all five of their questions correctly, they will advance into the ball pit and attempt to collect as many silver balls as possible. The quality of the prize increases with the number of silver balls collected. If the time runs out while a contestant is still in the chair, the contestant will get thrown into the foam or gunge tank below him. The end of show klaxon sounds like a car horn beeping.
A 30-minute documentary was produced in 2005 going behind the scenes of the programme.
Recorded at Antena's studios on the Cibyn Industrial Estate in Caernarfon.
