Going to a birthday party for a girl in my son's class, she's turning 3. I know she likes moana, and I wanted to get her a moana duplo which apparently doesn't exist. I found this one on amazon but it's regular lego. Would you be annoyed if someone got your 3yo this? She doesn't have younger siblings.

Any other ideas much appreciated. I know the party is Little Mermaid themed, and it's at a local nature center.
