Mr. Friend

"Mr. Friend" is the name of a robotic toy found in the video-game Rugrats: Search For Reptar - however the toy has malfunctioned and instead of being a plaything it has become a kind of mini-boss that spawns multiple versions of itself while attempting to actually harm Tommy while spouting out strange songs and rhymes: Tommy uses small cans to knock the robots over and destroy them but if they touch him they cause him to take damage.
