Why it worked
The video uses a high-energy, visual demonstration of a toy's features in an outdoor setting, making it immediately appealing to the target audience of parents and children.
Product placement
(a) Ruko Smart RC Dinosaur: It ACTS as it is unboxed, operated by the creator, and demonstrates its movement and shooting features. Removing it would change the entire video. (b) Ruko: The brand name appears on the packaging and is the creator's handle; it is the manufacturer of the product.
