—Robber Imp's splash screen
Robber Imp is a Bank Zombie in Plants vs. Zombies 3, which you can first encounter at Floor 30 of Devour Tower. He puts the first plant he encounters in his sack, making it unable to do anything, then he will run away with it. If he is defeated while carrying a plant, said plant will be released.
True to his name, he's based off a robber, a person who steals items for personal gain.
He is appropriately encountered in Lawn and Savings Bank, as robbers are often associated with banks.
He can be very annoying, as not only he has stealth threat, he can also steal a plant, you can use spikeweeds to effectively counter them, as they attack very fast and have "anti-stealth" characteristic. Potato mine can also be used against it since it can also kill several Robber imps in one tile
