ExplodingTNT is a "CraftMine" (Minecraft) youtuber who loves cheese because he is a dumb stupid mouse.
Overall, he doesn't like it when the robotic "prankster gangster" PinkSheep takes over his channel, and doesn't like prankster gangsters like PinkSheep too.
Why he is a mouse
He was found in the sewers by PinkSheep after he lost his mustache trimmers. But PinkSheep knocked the mustache trimmers out of ExplodingTNT's hands because he didn't want mustache trimmers from a "mouse". He likes cheese too.
