Barrier Snails are found in the Sea of Music and Mysterious Ridge in Ecco Junior. They barricade the path of dolphins. All shells are impermeable except the flashing shell. The colour shell that flashes varies and switches over time. The flashing snail can be pushed away by swimming into it. When only two snail shells remain the whole line collapses, but all snails return when the player swims far enough away. A different type of Barrier Snail also appears in the game, but these invulnerable snails must be swam around.
