Here’s a cute take on eco-friendly kids toys that’s both fun and innovative. U.K.-based, Little Baby Company, markets these over-sized kids play structures that are constructed of durable, 100% recycled cardboard.  The biodegradable toys come flat-packed and can be easily personalized by your resident young genius with a pack of crayons or a glue gun.

Many of the structures are big enough for a toddler to get inside to experience a valuable simulation of cramped apartment living they may face later in life.
