Dr Trayaurus

Dr Trayaurus is Dan's trusty lab partner. He is found in Dan's mod showcases and custom mod adventures. He is often blamed for messing things up but in the end he and Dan always make up. Trayaurus can be found in any mod themed showsowcase video and even has a couple videos just about him.
