  • I love it!
What a great build! I loved the complexity of the build and how nice it turned out. I have it displayed up on my desk and wish I could build more sets like this. It looks so smooth and realistic.

  • Great daddy daughter time!
Me and my 8 year old (who loves Otters) built this in a few sessions over a weekend. She loved seeing it come together and helping build it. A great exercise for kids in learning to follow directions and patience. The finished piece looks fantastic and will be displayed prominently in her room for years. ... show more
