Mo had a plan for this whole potions collection process. First, obviously, he needed to figure out the best path for hitting all the likely spots within the 45 minute time frame, not to mention hitting up some of his favorite spots in general, since he was slow to visit on his own. Like, for example, the creature sanctuary. Maybe the professor had changed and taken away all her creatures with her, but the new one had her own supply.

And some new and different ones!

Mo glanced around, noticing several of his classmates were going after some pretty standard and important ingredients: flobberworm mucus and various feathers and things. If this was really some effort to restock the potions cabinet for free, Mo was going to try for something more... unusual. No guts, no glory, right? So then... what... should... he...

Mokes! Really, MOKES? Mo tried to sneak up on their crates, knowing that mokes were pretty reticent when it came to humans. He must have made SOME noise because all the little lizards had completely disappeared by the time he got there. Someday, he would befriend them and become their kiiiiiiiiing. MARCUS BRANXTON, KING OF THE MOKES. It had a ring to it.

The good news was that the lizards had left behind something in their crates - patches of the silvery-green skin that had been shed as the creatures grew. Mo carefully retrieved several of the biggest patches of shed skin and put it into a bag in his satchel before he added some feed to the crate. There now... friends?
