Today on Toys & Stuff we feature a nifty Mattel Hot Wheels Flintstones Flintmobile. The toy dates from 1994 and while it is clear that it is a Hot Wheels toy, it also appears to be a cereal premium. The back side of the packaging states: "Keep a lookout for more fun stuff from the Pebbles Bedrock Shop-exclusively from Fruity and Cocoa Pebbles cereal." If that is the case, then this must have been a mail-in premium as it is far too large a toy to have been packaged inside the cereal box. I would be interested in seeing a copy of the cereal box showing this offering! It also has a color-changing feature. Dunk it in either warm or cold water and it is supposed to change colors, however I personally haven't tried it. It is a terrific addition to any Flintstones collection!
