I've always wondered what the hell poffins really were in the Pokémon series. The easy in-game solution is that they are berry-based confections you make and feed to your Pokémon, but that doesn't explain exactly what they are. I understand their basic function but not what foodstuff a poffin should resemble. 

Gourmet Gaming's filled pastry concept is much better than the idea I had that they were strange, berry-filled jigglers. 

I know from experience how much real animals love pastries. My Lickitung-like dog has lightning-quick food reflexes whenever donuts or imitation crab meat is involved. If she had real Pokémon powers, I'd be doomed.
