He's probably going to invent a deodorizer so that he can remove the scent. Or maybe he'll cook it in a very fragrant dish so that way the bees aren't able to smell it.
I hope we will see a small panel explaining it was just a silly mistake from the royal cook, forgetting the main public of his shop and not an actual back-handed gift (who wouldn't make much sense imo) later on.
So, even the chef use magic to make the impossible possible, maybe cz Yoshi cant use magic his creativity didnt get bounded by the norm thus his imagination soared in that world...
@.@...
How's he going to test it?... Is he going to create one failure at a time, making a different person act as the taste tester until someone doesn't get attacked by bees?... and all the fails just have to wait it out?
Or will he stink someone up, then try to find a way to unstink them?
