Melanie's new horse is named Hi Jinx, and he sure lives up to his name!

Now that Image is injured, Melanie needs to find another horse to race. She hasn't found one she feels really connected to just yet. But all that's about to change.

While visiting Image at Townsend Acres, Melanie meets a gorgeous brown Thoroughbred named Hi Jinx — he looks just like his ancestor, the famous racehorse Seabiscuit! Melanie feels an instant bond with this powerful animal. She and Jazz have been talking about owning a horse together, so why not this one?

But before they even get back to Whitebrook, Hi Jinx starts acting up — big-time! Will Melanie be able to get him to behave before it's too late?
