The Mysterious Package is a 1960 short.
Boys start disappearing after opening boxes addressed to them containing space helmets. When Mighty Mouse puts on one of the space helmets, he's drawn to an old castle in outer space, and learns that a metal monster is responsible. They fight, and after one final blow, the metal monster transforms into an old man. He thanks Mighty Mouse for breaking the spell, and he explains that an evil witch cast a spell on him, and he spent 100 years in lonely isolation as a metal monster, and Mighty Mouse's superhuman strength set him free. Mighty Mouse asks about the children, and the old man shows them the play area, where they're riding on amusement park styled planes. Mighty Mouse brings their playground back to Earth, and the parents are happy the nightmare is over.
