Just discovered this show today it seems to have a lot of great mess. Only one full episode available on YouTube that I could find. The first half of the show is bands/music videos and then the mess starts around the 43:00 mark

There is a streaming app called RTVE Play that has every episode available with no VPN needed. Haven't had a chance to dig through them all yet but the few I watch were good.

Thanks for sharing, looks promising

Good find - hadn't heard of this one.

Any idea what episode has the women dunking their heads into the pink mess?
I've always enjoyed those kind of scenes on any gameshow, particularly if the substance really sticks. It's also something that doesn't seem easy for producers to replicate well.... including yours truly. (I've tried MANY times over the years, with mixed results.)

Messy segment starts around 38 mins. Annoyingly the player doesn't show a thumbnail when hovering over the time strip.

This episode was great too. A pie game followed by a gunge game.
