Composer Figurine can be found in the Flathill portal world on top of the white-colored server in the far left corner of the final room before the exit portal.
Do note that the figurine is in the line of sight of the idle Composer present in this room, and jumping to the server will alert it to your presence. Don't forget that you will need to package the figurine before picking it up. While the Composer can't grab you as long as you are on the server- instead opting just relentlessly to swipe at you with its claws- it will go back to trying to grab you once you drop back down, so it's recommended that you duck into the vent to the left of the elevator to avoid getting caught once you've gotten the item.
