Perusing my copy of Tanteidan Magazine #163, I came across a cute 2-part model that I thought I should try:

Using orange for the fish and blue for the waves seemed to make sense at the time.

This is an action model – you grab the handles of the waves and, by working them like scissors the fish moves forwards and backwards in a pleasing way.

It is common to find lovely little charmers in the first few pages of a Tanteidan, often modular, often quirky but usually fun to fold.
