EUGY - a super-fun 3D puzzle that's eco-friendly and can be assembled in 10 to 20 minutes! This collectable toy is great for STEM concepts and craftable fun. This Sloth puzzle is quite the layabout, lying on its stomach with its arm dangling lazily. These famously slow mammals can reach speeds of up to 0.17 miles per hour (when they're really trucking). This 3D puzzle is a perfect activity to help pass some time and teach following instructions.
