The last part was the toy rack; it was needful (throwing all our stuff in a drawer wasn't a good way to maintain quality toys, and made for a damn pain whenever I wanted a specific item) and all the lumber was left over from the bed (and some pieces from other projects). It uses a plethora of hooks and a pre-fab towel rod to hang toys from, and the top part is a shelf. Bits of chain connected to eye-bolts holds the pieces together (for a properly dungeon-industrial look). Unlike the bed, this one was a lot easier than it looks!
Edit: added a larger version of the rack, to show the details.
