“43305 Piglet’s Birthday Fun follows the exact same format as 43300 Winnie the Pooh, with a brick-built character, side build with interior, and an accompanying character. But this set is 9+, so it’s aimed more at play than display. This means that Piglet is a much simpler... More build than his friend but is more easily played with. Poseable elements here are the head, ears, arms and feet, and Technic pins in the hands let him hold accessories.”

“43305 Piglet’s Birthday Fun also balances play and display. Aimed at those aged nine and up, the posable Piglet has a movable head, ears, arms and feet and comes with a buildable birthday cake – a tribute to the 100th anniversary this year. Just like the pot in 43300 Winnie... More the Pooh, the cake opens up to reveal Winnie the Pooh’s house on one side and the Hundred Acre Wood on the other, as well as a minifigure of Piglet.”
