2013 Trackmaster Exploding Bash (Used). Bash is battery powered and requires two AAA batteries (not included). Bash has a button on his front bufferbeam that, when pressed, splits his cab in two and flips his happy face into a dirty surprised face. Bash has been tested and works well. He has been lightly used and is in near mint condition. I'm trying to thin down my collection to help raise money for college as well as clear up space. For these reasons I will not be accepting returns.
