Monster Jam Dragon Reviews
Brick Fanatics
“LEGO Technic’s Monster Jam range includes 42149 Monster Jam Dragon, featuring horns, wings and intricate design using sticks as well as an alternate crocodile buggy build.”
Brickset
“Monster Jam is an unusual license for LEGO to acquire—although it may be incredibly popular in the US—but I have to admit that I think it's perfect for small these pull-back-and-go builds. Each truck is distinctive, with bright colors and detailed stickers, and the... More alternative models are a nice touch. For small sets, it feels like you get a fair amount for your money, and they're great to play with in pairs, facing off against each other across the floor.”
