The Veggietones

The Veggetones are a group of singing vegetables hired by Funella Furchester to sing at The Furchester Hotel in the episode "The Veggietones."

They're brought on to make people happy, however they end up doing the opposite by singing at inappropriate times, waking sleeping guests and interrupting tea time. Elmo Phoebe and Furgus suggest moving them into the newly fixed lift, until Mr. Snorkel refuses to leave so he can continue to hear them sing, causing issues for other guests wishing to use the lift, and hear the Veggietones.

Elmo and Phoebe finally come up with installing an area in the lobby, so many guests can hear them, and be happy.
