Wild West Wyldstyle
“Act like you belong here.”
The streetwise and free-spirited Master Builder called Wyldstyle knows the best way to escape from Bad Cop and his robot goons. Blasting through a secret portal, she and Emmet travel to the Wild West, a rootin’, tootin’ realm of cattle-rustling, train-robbing, and high-noon showdowns.
Donning old-timey disguises to blend in with the local cowboys and outlaws, they start their quest to find the wizard Vitruvius and save the LEGO world. But although Wyldstyle knows exactly what she’s doing, poor Emmet may be completely out of his league!
