I don't think it's a ton of mucus, but I don't really have anything to compare it with. But even when I was pushing against his mouth and his bottom jaw with the q-tip no mucus dripped/squeezed out of his mouth or anything.

His temps are 79-81 in the cool hide, 88-90 in the hot side. He has a UTH on a thermostat for the hot side, and I have a heat lamp on it to keep cool side and ambient up to 80. His humidity is at 60% now. I had it a little higher for a few days last week (around 70) because I thought he was going into shed.. Now I think it's just the stuck eye cap so it's back down.

Before I got the aspen out I'd noticed the past few days he'd been cruising around the tank and rubbing the sides/front of his mouth against the glass a lot - almost like he was trying to get rid of the aspen? Since I got it out though he's stayed in the hide. I'll definitely keep an eye on him, he's supposed to eat tomorrow and he hasn't missed a meal yet, so I hope that's a good indication that he's not sick.
