Hedgehog Monument [Kiev, Ukraine]
This monument is dedicated to the main character of a popular Soviet animated film called "The Hedgehog in the Fog".
The monument is made of wood and screws that simulate the spikes.
Interesting fact: Seth MacFarlane, the creator of Family Guy, is a big fan of "The Hedgehog in the Fog". The film was even referenced in Family Guy (season 8, episode 3).
