I used to have two Moschops. My female, Chomp Baby, was a god send. She would harvest so much materials for me and was loyal to me. Then there’s Mark. Mark is useless. He has been on wander for 30 in-game days. He hasen’t moved an inch. I double checked to see if he was on wander. He was. He was just so lazy, but I still kept him. As a fridge. Then one faithful day, Chomp Baby was gathering for me when she somehow angered a Trike. I watched right before my eyes how the best gatherer I had died. Now Mark was not sad. Mark was too busy being lazy. Mark is not a good gatherer.
Feeding it what you want it to gather has NO EFFECT on its father rates. These are determined by the additional level granted every level to increase your moschops' gathering efficiency of your chosen resource.
Best for if you need fast polymer for crafting. I have used this countless times to make all the industrial equipment. But only level up health and weight and put the gathering levels into polymer. Mines at 530% and I get 50 polymer per penguin. ðŸ‘
