LEGO(R) Creator Fierce Dinosaur - 31379

Bought this for my 9-year-old and the three-in-one build is what sold me—he rebuilt it as the T. rex first, then took it apart to try the other two options without losing interest. The joints hold poses well, so it's still standing on his shelf weeks later.

My nephew spent a solid two hours on the T-Rex before he even asked about the other builds, which never happens with him. The joints actually hold their pose, so it's been standing on his shelf menacing everything for a week now.

The three-in-one build is what sold me — my kid rebuilt it into the T. rex first, then spent the whole afternoon on the other two versions. For the price, getting three separate dinosaur builds out of one set is honestly a steal.
