Shrinking Sukiyaki

Shrinking Sukiyaki is an invention of world renowned scientist Dr. T. Garden; once eaten, Shrinking Sukiyaki causes the ingester to shrink to miniscule size, for at least a week.

Shrinking Sukiyaki appeared near the end of The Super Mario Bros. Super Show! episode "Mario Meets Koop-zilla / Fortune Teller"; Mario, hungry after having recently defeated Koopzilla, searched through Dr. T. Gardfen's laboratory and found some Shrinking Sukiyaki, which he proceeded to eat. It was only after Mario ate the Shrinking Sukiyaki that Dr. T. Garden told him of it's effects, also revealing to Mario that there was no cure for Shrinking Sukiyaki and that it would take a week for it's effects to wear off.
