Cashbots are all about money, according to the toontown players guide they would sell their mothers, if they had one. The head of the cashbots is the CFO and their headquarters is located at the end of Pajama Place in Donald's Dreamland. They're most commonly found in Donald's Dreamland, Donald's Dock, and Minnie's Melodyland.
"I've got a train to catch!"
The CFO is the head of the Cashbots and my by far my favorite Cog boss. He looks the goofiest and seems the most harmless out of the 4. And even though I've never played through it, his boss battle is also the funniest, it is literally just him getting bullied. It ends with him getting hit by a fucking train, which still makes me laugh to this day.
