地形公園

My kid has been launching his robot off the two ramps for hours, and the rails actually stay put instead of sliding around. The five setup options mean he keeps rebuilding it into something new, so it hasn't gotten boring yet.

The two ramps snap together in a few different ways, which kept my son busy reconfiguring the setup instead of asking for new toys. Only wish the rails clicked in a bit more securely, they pop loose when the robot hits them at full speed.
