Seapals are a range of marine creature-themed soft toys, made by the generally-higher-quality-than-average American manufacturer 'Russ Berries', also sometimes known as 'Applause'. A range of brightly coloured tropical / coral-reef fish are depicted in the range, as well as other popular sea creatures such as sharks, turtles, manta ray, etc.
The toys are each about five inches long and nicely made out of good-quality short-pile fur fabric. They are well-sculpted in a cartoony format, but have surprisingly accurate depictions of the various fish body forms, embroidered adornments, fins, etc.; this is a rather impressively-made range, all in all. The toys are notionally finger-puppets; each of them has a finger-sized hole concealed somewhere on the underside, that you can use to stick your finger in and then jiggle the fish back and forth. As these are relatively large soft-toys - out of the finger-puppet scale range, I'd say, this feature only works to a limited extent.
The toys are intended for kids aged four and up - probably because of the potentially-detachable eyes, which are large and typically are made of transparent coloured plastic. To increase their appealing expressions, most of the creatures have an 'eyelid' added to give more of a cute expression (rather than your typical fishy 'Shadow Over Innsmouth' look).
I came across these toys remaindered in the local pound shop (!) but they currently sell for surprising prices - around the £7 to £10 mark - on amazon.co.uk. The mark up is presumably because each creature comes with a 'code' that can be used online to 'unlock' games etc. at the Seapals website where kids can 'create a virtual aquarium'; not a feature I've tried out myself, but I suppose it might be a selling point for some.
These are very nicely designed and made, attractive toys. I would say £7 to £10 is far too much to pay for one - but I was very happy with the £2 Purple Tang I got at the discount shop.
