TOM AND JERRY: BACK TO OZ is the animated sequel to TOM AND JERRY AND THE WIZARD OF OZ, which finds our classic cat and mouse frenemies joining Dorothy and Toto on her MGM journey.
In BACK TO OZ, Dorothy has just returned to find nobody believes her tale. Even when she has the ruby slippers to prove it, there's justification for why her story of Oz is just a fancy.
But Dorothy doesn't have time to worry about convincing Uncle Henry, Aunt Em, or the farmhands, Hunk, Hickory, and Zeke. She and the Gale family are still cleaning up after the twister when they find themselves on the verge of losing what's left of the family farm, when neighboring Mr. Bibb (Jason Alexander) files a lawsuit claiming that the twister released some of the Gale pigs who then plundered his prize watermelon patch. Knowing the Gales have no financial resources, he's willing to take his payment in land and livestock, giving the family 24 hours to find a way to pay him otherwise.
