The fluidity of sand and water makes for a fascinating time of adventure and fun. Step 2 has taken all that fun and sized it perfectly for toddlers to enjoy hours of playtime. The set itself is easy to assemble, made of high quality plastic impressing our testers with its sturdiness. Apart from just the sand and water there is a train set including both a train and tracks. The filling station is a great manipulative that never seemed to get old. Parents loved the thoughtful design element of placing an umbrella holder (umbrella not included) in the middle of the set so that children can play outside protected from the harmful rays of the sun.
