Test-o-Track

The Test-O-Track is an area in Banjo-Kazooie: Nuts & Bolts allowing players to test custom built vehicles before saving them and using them in the single-player missions and Multiplayer games. It is located in Mumbo's Motors in Showdown Town. It features various areas including a pool, a steep slope, aerial testing tracks, and ice to test a vehicle's compatibility with each feature. Some of the other attractions include a loop-de-loop (which can be successfully completed, but pretty tricky), a rocky ground area resembling rough terrain, a snake tunnel (which will do quite a bit of damage if you go in loops if your vehicle wasn't built right), a raised level where most of the ramps go to (and above this area the aerial testing tracks can be found), a ring area above the rough terrain which grows and shrinks in certain set places, an area filled with water, some icy/snowy ground, and a main field where the player starts out at with land vehicles. There are several soccer balls as well, one in mid-air, one in the water and the other on land.

The Test-O-Track has no missions or characters featured during normal gameplay, however, by downloading L.O.G.'s Lost Challenges, the player can add various missions to the area for more Jiggies and Achievements.
