When hatching a giga egg on mobile you will need about 7-10 standing torches (Angler Gel reccomended) and then you need to wait 5 hours (be very careful if it’s too hot or too cold) this is going to take a while, If you want to fully imprint. Make a save file about 20 seconds before the egg hatches and then keep restoring save file until you get the cuddle or walk ones, then after doing that you wait for 30 minutes then save data in about 20 or 10 (depends on you) seconds before the imprint quest finishes you just keep restoring data until you get cuddle or walk and repeat. Congrats you now have a 100% imprint giga
