How to use: First, if you want to transform the Bumblebee toy, it only takes 5 steps to turn it from a sportscar to a robot. For the Grimlock toy, you'll need 8 steps to change it from a T. rex to a robot. To create the Bumblegrim figure, combine the Bumblebee and Grimlock figures in 6 steps. You can also combine these figures with other Crash Combiners figures (which you need to buy separately) to form different 2 - bot combinations. Note: This product is recommended for ages 6 and above. There's a choking hazard as small parts may be generated, so keep it away from children under 3 years. Maintenance: Keep the toys in a dry place to avoid damage. When not in use, store them in a box to prevent them from getting lost or broken.
