Is Cooper the STEM Robot worth it for a 9-year-old?

Does it need batteries?

Yes for the light and sound features. The listing says batteries are required but not included, so plan to add them before first play.

Is it compatible with LEGO?

Yes. The listing describes the interlocking blocks as LEGO-compatible, so the pieces can be combined with a existing LEGO collection.

How big is the finished T. rex?

The T. rex model stands over 18 cm (7 in.) tall. The full package weighs 1.32 kg.

The building set, a hammer accessory for Cooper and a bow accessory for Zoey. Batteries are not included.

How many kids can play at once?

The set is listed for 1 to 3 players, so it works for solo building or a small group.
