Monkey GO Happy Stage 743: Interplanetary Chapter — 11 · game online
On the eleventh planet, there resides a robot whose creation raises many questions about its purpose, but nevertheless, it still exists.
First, you need to locate the whereabouts of this robot, and then gather two parts of a special key to unlock the doors.
Currently, only two locked locations are available, but they can be easily unlocked by paying attention to the scrolling text on one of the arenas to find the correct combination. Once everything is accessible, you'll be able to connect with the local inhabitants and exchange both found and acquired items.
