Zach is a human boy.
Invited to Mickey and Minnie Mouse's Halloween party at the Haunted Mansion in 1998, Zach soon teamed up with Sally and Sam to find the perfect Halloween costumes, and to discover the source of the mysterious voice guiding them along. After being outfitted with a skeleton costume, Zach & Sally joined the rest of the party guests in trick-or-treating in Toontown, and then dancing to The Monster Mash in the Mansion.
Behind the scenes Edit
Zach appears in the 1998 live-action film Disney Sing Along Songs: Happy Haunting: Party in Disneyland.
