Just when you had moved past your envy of the proud owners of than that custom Groot swing, Super-Fan Builds comes along with another, even cooler project: a one-of-a-kind Batmobile stroller, designed to look like the Tumbler from the Christopher Nolan films.

Constructed by Hollywood pop company Tim Baker Creations as a surprise for father-and-son Batman fans, the stroller is on a steel frame, making it well-suited for those danger-filled walks through Gotham City Park or, I don't know, Toys "R" Us.

Of course, as Toyland notes, figuring out how to transport the thing -- not to mention store it -- may require the mind of the World's Greatest Detective.
