HINT: the pause plug freezes the game, allowing you to think about your next move without rush, and then just keep that plug for that socket and unplug it to make the patchlings move, and plug it back in to change any other plug around. Then pause the patchlings whenever they get close to either the red or blue platform so you can send that specific platform to where it needs to be :)
(I also struggled with this level hahaha)
