Easy venom farm : 1. Get light pet 2. Go to where nameless spawn (red or blue zones) 3. Wait for about 10 to spawn and make sure one is red 3.5 (optional) drag them near your base, they wont go in green zone 4. Turn light on 5. Kill all but red (or atleast leave one alive) 6. Wait for it to burrow 7. Repeat steps 3-6
They lose 1 point of food every 15 seconds, so to time how long until they start starving, multiply their current amount of food by 15 and then divide by 60 twice. This will give you the number of hours left untill the food stat reaches 0.
((15 x food)÷60)÷60
