|Behind the scenes information|
They serve as the second boss in Ty the Tasmanian Tiger 2. Once they are defeated, they sink into the ocean and swim away back to Fluffy and Cass, as it turns out that they were simply a distraction for Ty while Fluffy and Cass stole and important item from the factory.
Buster once more returned to fight Ty in the last level, though this time much weaker due to Ty's being in a Bunyip. As such, Buster went down with only two hits.
The nano-bots (possibly a different batch) appeared in the final boss battle, this time as green and purple, crab-like robots that would engage in a variety of attacks against Ty's mech, such as forming tornadoes. They eventually surrounded Boss Cass' hoverchair to give him a mech of his own to fight with, but were defeated. They fell into the lava below as Cass escaped the mech, and perished accordingly.
When they roar, him them in the mouth.In the final battle, let them punch the ground so therie arms get stuck. Walk up their arms and punch them in the head.
