The Peppa Pig George's Band Set includes castanets, cymbals, a drum, maracas, a trumpet and a tambourine and none of the instruments require any batteries, but on the down side, that also means they don't have an off switch!
They seem to be pretty good stock levels still, although it's dropped somewhat from when I checked this morning.
Commenters on the HUKD threadthat own it say it's a good purchase, (although there's talk of headaches – but the kids love it).
This is available for home delivery too, but will cost you £5.95, which is a little rough compared to the actual item price though! Of course, you can reserve online, and collect in store, which certainly seems the best bet here!
