Using these Dino Troop dinosaur toys is super easy. Just pick up a dinosaur and let your child start playing. They can make the dinosaurs move according to their unique features, like opening the GALOSAURUS's mouth or making the ANKYLOSAURUS swing its tail. When it comes to safety, make sure to keep these toys away from small children under 3 years old, as they may pose a choking hazard. For maintenance, you can use a soft, damp cloth to wipe the toys clean if they get dirty. Don't submerge them in water, as this may damage the internal mechanisms. If you have any preferences for specific dinosaur styles, remember to add a note in your order. And if you want to be sure to get the style you like, it's a good idea to visit your local Toyworld store.
