Tank Banjo is one of Mumbo Jumbo's transformations in Banjo-Kazooie: Grunty's Revenge. When Mumbo turns Banjo into a tank, he gains the ability to crawl across toxic chemicals without worry. The tank also is armed with missiles, which kill enemies and open special tank-only doors located in Grunty Industries and Bad Magic Bayou. The only downside to the tank transformation is that it cannot jump.
