Morphing Paper Fish

Description:

The main part of this toy is a piece of corrugated paper that can flex into different shapes. However the addition of a fin and a pair of eyes makes it into a kind of a fish! Squeeze the tail and the mouth opens, in quite a realistic way. But Tim always likes exploring new options, and the toy can be folded into a hat, rather like the traditional pith helmet that was worn in the tropics. But there's more... fold it another way, and you get a very strange hat, where the eyes give a very strange effect indeed!

This toy was bought back in 1995, and has not been available for a long time now.

And now I feel like opening up Tanteidan Convention Book 14 and fold Mabona's Puffer Fish:
