There have been copies of the original elf popping up on eBay lately but they get taken off really quickly so you'd have to keep an eye out. I've seen lots of elf toys in garden centres this year too.
Mostly we just hide our elf but sometimes he gets up to things...
Got ours from Simply Clintons for £5.00 and he is lovely looking https://www.clintoncards.co.uk/catalog/product/view/id/46077/s/12cm-dangly-elf-boy-winter-wishes/
