Michael has a downer food. Grape soda makes him super hyper and crazy, Lemon soda makes him super mellow and sane.
Just like Michael, Ritchie has foods that makes him hyper and mellow. Only different is with Michael depending on which soda varys his craziness or mellownesd, Ritchie it's maxed on direction or another.
If one has took the food that max their hyperness, the other goes a little hyper too. If they both have the food that maxes the crazy, your doomed.
Same applies to the calming food, just you can't get them to move or do anything on their own when they both have it.
