They've also been reduced down to £8.99 at Smyths Toys too; prices elsewhere vary between £10 and £17.
Each, rather quirky looking, Sing a ma Jig chatters and sings their own song when you press their tummy.
The other rather clever thing they do is sing in harmony with each other when they're together with other Sing a ma Jigs.
When they're talking, they speak a language of jibbers and jabbers and in song mode you can also control the tempo of the song.
But it's the harmony mode that I'd love to hear the most - with someone else's Sing a ma Jigs though, I imagine two or more of these guys singing away in harmony, even if they are pitch perfect, would wear a little thin after a while.
Reviews from parents of existing Sing a ma Jig owners have nothing but praise for these little singing characters.
There are five of them to collect, if you fancy your own Sing a ma Jig choir, and they come with the batteries they need.
Home delivery with Smyths Toys will cost you £4.99, so it'll be worth checking HERE to see if you've got a store close by so you can collect your Sing a ma Jigs for free.
