Piranha fish have something of an undeserved bad reputation. But this unfortunate creature, built from LEGO by Sebastian Gren, certainly looks like he come off worst in an argument with his fellows. This is a fun model, but it’s well-built too. The bones of the skeleton are perfectly-arranged, with the use of a LEGO fibre-optic cable to provide a flexible spine, and the face has plenty of ugly piranha character. The presentation helps as well — the simple base, with its touches of greenery, effectively suggests an appropriate river bed base.
