While Regect THEORETICALLY doesn't need sleep, I feel like he still wouldn't miss a single opportunity to take a nap. It brings him peace and quiet, something that everyone needs once and a while, but especially him with all of the drama that is happening recently. And as proven by the latest episodes (we don't talk about the latest episodes, we all cope in unison) Regect deeply cares about his two friends. Just like a cat, he would rather sleep next to someone he entirely and wholeheartedly trusts as he is ''exposed'' and thus vulnerable.
Ze, who apparently forgot about that, had the AUDACITY to seat down his own bed in his own room and close his eyes for less 30 seconds. Of course, you can imagine Regect sensing that there is far too much peace in this house and, his zoomies activating, ran up the stairs at full speed and threw himself at Ze. And obviously, he annoyed the player for at least half an hour before settling down.
Ze had to wait until Moe came home to drag him out of that pile of whatever Regect was (because apparently that dummy had purposely gotten heavier with his shape shifting abilities to mess with him). And sure enough, Moe just joined the cuddle pile and dismissed Ze's groans and complains, as the great friend that she is <3
