To use this product, first grab the excavation tool and start digging through the rock, sand, and slime. Be careful while digging to avoid damaging the fossil pieces. Once you've found all the pieces, assemble them to create your dinosaur skeleton. When you're done assembling, give the dinosaur's tail a pull to see its eyes light up and hear the roar. For maintenance, keep the toy away from water as it may damage the electronics. If it gets dirty, you can use a dry cloth to gently wipe it. Don't try to take the toy apart unless it's necessary for cleaning as it may void the warranty. And remember, there are four different dinosaurs to collect, so have fun finding them all!
