The product description mentions adult assembly required, as do all of the other imaginext products we have purchased in the past. What it doesn't say is the shock one feels when opening the box to be confronted with a multitude of nondescript pieces. The instructions are images of line drawings left to be deciphered by the user since none of the pieces are labeled or in any type of order. After attempting to decipher, assemble and then realizing that assembly would not stay together in this poorly designed toy I reboxed the pieces and called it a night.This item is not even close to being the quality of the dragon castle, batman, space shuttle and accessory pieces in the other imaginext line.
