transmutazors

There were 20 story books to collect

I only have the one book (pic below)

Both the original dinosaur model & their mutant came in a packet together.

'Millions of years ago, Dinosaurs ruled the Earth. Now mutations are being
discovered all over the world having adapted to today's environment.
You can paint your TRANSMUTAZORS to look like the pictures.
Collect the cards and challenge your friends to a battle of the TRANSMUTAZORS.
Each player turns over one of their cards and the winner is the one with the
highest power rating.'
