Soak a spring roll wrapper in a bowl of warm water until just pliable, about 30 seconds. Gently shake off excess water, and place onto work surface. Place some of the sliced lobster, avocado, mizuna, mint, sea vegetables, heart of palm, and mushrooms in a strip on the bottom edge of the spring roll. Fold once towards the center, then fold in the sides and continue rolling into a cylinder. Repeat with remaining ingredients.
