Model by Eric Albrecht
The 8229 Tread Trekker is a very unusual convertible vehicle, not necessarily based on anything real.  The tracked vehicle uses the new rubber tracks and sprockets and includes a Technic figure.  The upper part of the vehicle detaches from the base and becomes what appears to be a boat.  Though the topic is unique, this Tech Play set is pretty simple and offers limited functionality but a good selection of the new parts.

Features
Modular Watercraft
The tracked base unit can be separated from the watercraft using a small ball gear in the back.

Canopy
The canopy is constructed from the new angle connectors and can be opened using a knob at the back.  A worm gear drives a 24 tooth spur gear to lift and hold the canopy.
