Royal Cow
The Royal Cow is a large, brown cow wearing a crown which was once the pet of Princess Toadstool.
In The Super Mario Bros. Super Show! episode "Mario and the Beanstalk / Bats in the Basement", Princess Toadstool, needing one hundred Gold Coin to save the closing Mushroom Kingdom Orphanage, made the descision of selling the Royal Cow; after making this descision, Princess Toadstool intrusted Mario and Luigi with selling the Royal Cow.
Taking the Royal Cow to a cow lot, Mario and Luigi began trying to sell it to the lot's owner, Dealin' Delbert, who kept trying to convince Mario and Luigi to trade their cow for several old and sick looking ones. Eventually, Dealin' Delbert made a "special deal" with Mario and Luigi, trading them something special for the Royal Cow.
It was later revealed that Mario and Luigi had, in actuality, traded the Royal Cow for three small Garbanzo beans; though Toad had originally planned on travelling to Dealin' Delbert's cow lot to get the Royal Cow back, he, along with Princess Toadstool, Mario and Luigi, were sidetracked by a giant beanstalk which had grown in their yard; the Royal Cow was subsequently never reclaimed.
