[No one ever needs to lecture Goku about eating well. Never. He will absolutely follow the cake/Sebastian to the table though, so at least there's that.]
Yeah, of course. I wouldn't eat it if it wasn't tasty. [Speaking of which- aah, more cake! Sits down to eat it happily. He can sort of get full, but so long as food is put in front of him he'll keep eating it.] Do you not like sweet stuff?
