DUPLO ***10842 BATCAVE CHALLENGE*** batman robin joker poison ivy superhero set

Retired set; includes everything shown in the photos. No original box or instructions.

Excellent used condition. Ships assembled & ready for play.

Almost complete, with these exceptions:

1. Missing one yellow "cannon ball" (includes one out of two). So I've added an extra cannon as a bonus.

2. For the base of the cannon, I've added several parts in place of the original blue 4x4 round plate.

3. Subbed one black curved brick for the original two curved bricks forming the bat mask center shape on the top of the building.

Plus I'm throwing in a couple of cool bonus batman-related bricks as well.

USPS priority shipping calculated by eBay; thanks for looking!
