Using this toy is a lot of fun. To start, if you want to build the Slugtron, take the Megatron and Dinobot Slug figures. Follow the 11 - step process to combine them into the 7 - inch Slugtron. When you want to transform the toys individually, convert the Megatron from tank to robot mode in 3 steps and the Dinobot Slug from triceratops to robot mode in 5 steps. You can also use the included fusion cannon and blaster accessories to enhance the play. For battle combinations, look for other Dino Combiners (sold separately) and combine them with these figures to create different 2 - bot setups. As for maintenance, keep the toy away from sharp objects to avoid scratches. When not in use, store it in a dry place. This toy is suitable for kids aged 6 and up, so make sure younger kids are supervised if they play with it.
