Back in 2020, the LEGO group partnered with Unbound to create an in-depth book. The subject was chosen by LEGO fans and the book was crowdfunded. One of the pledge amounts offered a very rare prototype element and here’s the first look at the said element. It’s a sort of springy pogo stick and features a working spring function. It can be held by a minifigure as well. Only 500 of the elements have been created and unlike normal LEGO pieces, this one has been 3D pieces similar to the recent LEGO House Duck element.
