This is one of the 1st Versions of the original 1967 Strange Change toys with the Strange Change Machine. The later edition changed the machine name to the Time Machine. This set contains a working heater, the original dome, and some of the original creatures. I think there is a red spider, red scorpion, red monster, red swamp creature, green dinosaur, green iguana,
The pieces are in Good Condition including the red heating element and plastic cover. The 1967 box is in good condition for its year but has some tape on it. The electrical works & heating element/burner works accordingly. I know it is missing some pieces like the green mountain, tweezers, plastic mat, and some time capsule creatures; therefore, I am selling it as is because I am not sure how many creatures actually came with it to say how many it is missing as well.
