## Description

Let your little builder get immersed in a race to a rescue a trapped dolphin and find the hidden treasure with LEGO Friends 41378 Dolphins Rescue Mission creative toy. This playset allows kids to act out an underwater LEGO rescue mission as Stephanie dives in her cool submarine toy craft to free a stricken dolphin from a shipwreck. The shipwreck’s mast is hinged so Stephanie can lift it with the grabbing arm of her craft. A hidden gem-filled treasure chest adds another dimension to the action, as does the textile pirate’s map that reveals secret information when brushed with water. But who will find the map first, Stephanie or bad-girl Kacey? The only certainty is the fun your Friends fan will have with this treasure hunt toy! Instructions PLUS is also great for younger builders, guiding them through the building process for a greater sense of independence and achievement. This adventure toy includes 2 mini-doll figures, plus 2 dolphin figures.

Review: I purchased this LEGO set for my daughter’s 5th birthday. She’s had a few of the Friends sets in the past but this one is her favorite by far. She was able to assemble most of the submarine on her own and loves all of the sea creatures and treasure that comes with it. She couldn’t get enough of the treasure map and the fact that when she puts it in water the map is revealed. My seven year old has enjoyed playing with this set as well (when my daughter is willing to share). This one was definitely a hit in our household.
Review: Nice set for a 6 year old. Part of the bigger 'Rescue' series which we have also collected. Gives a unique under water experience that is rare with lego sets.

### ⭐⭐⭐⭐⭐ Review
*by H***R on 1 February 2020*

This was a present for our Granddaughter, along with the lighthouse set. She really loved it. She had them both put together in under an hour and then played with them all day. Like all the LEGO sets, it was challenging and easy at the same time. The kids really learn how to follow directions and the importance of building in the proper sequence at a reasonable pace and not just hurry up and through it together.
