My 2 year old was so excited to build a fort with his daddy and help pass daddy the “green sticksand orange balls. They made a castle fort to match his castle themed room!The instructions were simple to understand and easy to put together! Just remember to our the arrow on the ball pointing up!My toddler is very rough when he plays, and be played king of the castle with his huge pirate ship and only one piece came loose, which did not effect the overall structure of the castle at all!But when it was time to tear it down for bed it was easy to take past and comes with a bag for storage!Also, while building the castle my son sang, “Bob the builder, can we build it, yes we can!”If we can build it you can too! Next we will probably take it outside an build a cozy igloo fort!So much fort building fun for years to come!
