S1·E47 Double una's Heaven and Hell

Cancer, who finds Ophiuchus's own personal money stash, uses it to purchase an ice-making machine and then proceeds to rampage through Echo Ridge with an artificial ice floe. Mega Man appears and rescues Luna from the wreckage, who was waiting for him to give him some food she prepared for him. When Mega Man later eats it, he's surprised to find it tastes delicious.
