Transformation Instructions & Description

Below is a picture of Slimestone in its Rock Form, and a picture from the Bandai catalogue.



In Japan, Slimestone was sold with a golden inner body, under the name "Magnarock".

Magnarock, picture: Dave Barry


This picture, taken from the early australian promo comic shows a prototype version of Slimestone, that has differences from the final release, essentially the head is different.

Sadly the picture does not show the prototype head in its full glory, but you can get an idea. The prototype head looks much meaner and evil than the released Slimestone.
