Conch Shell enemy line

The Conch Shell and Spiral Shell are species of monsters found in Golden Sun: The Lost Age. These monsters, resembling small snails whose "shells" are their own striped wormlike bodies wrapped in that shape, are palette swaps of each other and have differing levels of power and defense. What makes these monsters unique is that they appear in large groups between 2 and 5 individuals at a time.

Conch Shell
A Conch Shell is an orange member. The Conch Shell features 102 HP, 158 Attack, 43 Defense, 72 Agility, and ? Luck. It has strong resistance to Jupiter, but is less resistant to Venus and Mercury, and it is vulnerable to Mars attacks.

The Conch Shell can attack with a physical attack, and can use the monster skill Mucous Gel, which contrary to its name resembles blue steam gathering around and into a single Adept. Mucous Gel does no damage but may afflict Delusion.

Felling a Conch Shell yields 80 EXP, 81 coins, and sometimes, an Elixer. It is fought within Piers' Ship; what makes this monster especially notable is that many players never encounter it at all, because it only randomly spawns in the narrow hallways of the ship's interior in between the big rooms with all the Aqua Jelly monsters, not appearing in any of the big rooms themselves. Individual Conch Shells are quite easy to defeat.

Spiral Shell
A Spiral Shell is a blue member. The Spiral Shell features 155 HP, 268 Attack, 92 Defense, 117 Agility, and 9 Luck. It has strong resistance to Jupiter, but is less resistant to Venus and Mercury, and it is vulnerable to Mars attacks.

The Spiral Shell can attack with a physical attack, and can use the monster skill Poison Gel, which contrary to its name resembles red steam gathering around and into a single Adept. Poison Gel does no damage but may afflict Deadly Poison.

Felling a Spiral Shell yields 236 EXP, 129 coins, and in uncommon cases, an Elixer. It is fought all throughout the Great Western Sea while on ship, as well as when sailing through the Northern Reaches. If a lower-level party just enters the Great Western Sea and battles five of these at once, they could be quite damaging, though wide area-of-effect Psynergy like Mother Gaia and Cycle Beam would be ideal to take them out en masse. Individual Spiral Shells are quite easy to defeat on their own, compared to Turtle Dragons which have improved stats and abilities everywhere and have over twice as much HP.

Poison Shell
Like with all other monster lines introduced in The Lost Age that have apparently only two members, a third palette swap member to this line exists in the code of the game cart and was even given its own name, but has none of its stats and abilities coded beyond weak placeholder abilities. Had it been used it would have appeared as a turquoise member named Poison Shell.
