(Not) Breaking the Mould

Right after "the new campsite", and only if you have unlocked it (see the quest above for more info), Chet will have one peculiar quest for you (he is present only when there is still light outside!). He’ll ask 6 slime jewels to begin the… fun part~ which is using some moulds to make dildos out of most regular enemies you encountered in the game! You need to win by lust, since they need to be erect for the mould to work, so high CHA players will have a slightly easier time, but focusing on keeping your health up with bind up every now and then should be enough even against powerful foes and the tease-resistant lizards, and remember to rest at the tavern and jerk off every 1-2 battles, teasing relies more on luck than normal, after all.
There are 7 moulds you can submit: bull (only if their village still exists), rogue lizard (they need 2, due to the hemipenes), gargoyle (now out at night where you usually fight bulls and slimes), yeti (southwest of the village; requires 2 due to his size), mole (behind Kith/Kin, in case you missed them), shroom-berus (random encounter when picking mushrooms) and… yourself, as an option instead of masturbating. Chet does give you 3 moulds to start, but you’ll need 9 to collect them all, to get new moulds, give Chet 3 slime jewels for each (so 18 more, you can’t actually make duplicates, so don’t worry about wasting moulds).
You can finish the quest with anything between 0 and 7 moulds (6 if bulls aren’t there), Chet will pay 500 coins each (so, potentially, 3500 coins!), plus a level up point for at least 1 mould, and a stone dildo for at least 6 moulds (no use for it as of 0.34)… I'd personally count the extra collecting scenes a reward themselves too, to be honest~. (Do remember to submit them before finishing the quest!).
