Mad Mix Machine is an episode of Pocoyo.
Pocoyo finds a super duper machine that mixes objects and makes special new toys to play with. But when Pocoyo puts his friends' toys in the machine for fun, he upsets them. Eventually Pocoyo has to put things back to normal and then share his new magic machine with his friends so they can all enjoy it.
One of the songs played on the tradio/rumpet is the overture from Carmen by Georges Bizet.
