The Backyardigans: Cave Party

null: Furry pelts and primitive inventions - it must be the ice age!   Tasha and Austin live in a cave atop a mountain.  They invite the Valley Cave People (Tyrone, Pablo and Uniqua) over for a party.  As the Valley folks travel, and the Mountain folks get the cave party-ready, all inventing things as they go, Calypso music keeps them all moving.
