Description

With a comically inflated design, this cute little blowfish is loads of fun to build, loads of fun to play with, and educational too! The rounded body gives the Blowfish a unique look that differs from the flat designs of previous Robocraft models, and its transparent green plastic allows the inner-workings of the device to be easily observed. The tail fin’s neutral position can be manually adjusted to control the direction in which the blowfish swims.
