>>115582122Chibi Robo, only you're not chibi. Also you can actually communicate.
This includes the surreal insanity that ensues during your working hours.
Would lose a bit of the initial charm since a big part of Chibi Robo is, well, he's small. But I'm sure there's an angle you could pull that'd make it interesting. Maybe the mansion you work in is themed, a la Luigi's Mansion. As you fulfill your duties, you uncover some dark secret or unfurl a mind bending mystery.
Or just keep it wholesome and make it about improving your owners' lives while balancing your daily work, and the "fun" comes in by requiring creative solutions to their problems. Say the man of the house is having trouble figuring out what to get his wife for her birthday, so you just happen to catch a glimpse of something the wife is looking at on her tablet while cleaning, seeing she has a particular interest in a certain brand of purse. You can drop some manner of hint in the master's office, or ask a "candid" question to the wife about the purse while you know that the master is within ear shot, but not within sight. Or, just be direct and tell him, but this comes at the cost of him not feeling clever, or that he thought of it himself, possibly affecting future problems. Again, might be hard to make all that interesting, but I'm sure there'd be some way to make it engaging.
