For CJ's birthday back in January he received a Fisher-Price set of Trio blocks. For Christmas, EMan received a Peg Board set and both sets work perfectly together (coincidentally). This morning, "CJ the pirate" (no longer "CJB Batman the ninja who shoots fire") and EMan pulled out the sets which now live together in the trio blocks box.
After reading the instructions CJ decided to build a park with a pool.
EMan decided to build a tower.
And together they've constructed a fantastic park.
Play is the work of a child.
