Hop into the pool with Ackbar to collect the minikit.
Build three snowmen for the next minikit. Destroy the snow piles at the start and reassemble them into your first snowman.
Cross over to the right, where you have to build a contraption to save Finn. Keep going to right to find the parts for the second snowman. Do it before you save him or you'll miss your chance.

While Rey is fighting, switch to Finn and interact with the terminal behind the trees.
Scoot over to the right to find a shooting range of sorts. Shoot six targets for a minikit.

After falling down, you can make your way over to a ledge. Use a character with the ability to break cracked lego objects and smash open the wall here for the minikit.
From the ledge, hop back out onto the rocky outcrops and make your way to the right.
Pass through the toxic cloud with Finn and grab the minikit.
