Urchin Beast enemy line

The Urchin Beast, Needle Egg, and Sea Hedgehog are species of monsters found in Golden Sun: The Lost Age. These monsters, resembling very spiky sea urchins with two wide-open eyes, are palette swaps of each other and have differing levels of power and defense.

Urchin Beast
The Urchin Beast is a small member with a violet body. The Urchin Beast has 89 HP, 163 Attack, 54 Defense, 101 Agility, and 6 Luck. It is resistant to Jupiter and highly succeptible to Mars attacks.

An Urchin Beast can attack with a physical attack and the monster skill Beast Needle, which does somewhat strong damage to a single Adept and visually resembles a series of long purple needles shoot from the enemy into the target adept. This monster is one of the less remarkable sights and opponents that will be battled throughout the Great Eastern Sea.

Felling an Urchin Beast yields 93 EXP, 79 coins, and in somewhat uncommon cases, an Antidote. Urchin Beasts are battled all throughout the Great Eastern Sea as random battles while sailing on the Lemurian Ship.

Needle Egg
The Needle Egg is a small member with a bright yellow body. The Needle Egg has 119 HP, 234 Attack, 94 Defense, 147 Agility, and 7 Luck. It is resistant to Jupiter and highly succeptible to Mars attacks.

A Needle Egg can attack with a physical attack and the monster skill Poison Sting, which does somewhat strong damage to a single Adept, may afflict that Adept with Poison, and visually resembles a series of long green needles shoot from the enemy into the target adept with a green cloud emerging from the point of impact. This monster, which can be fought almost right after getting access to the Urchin Beast, is a somewhat more respectable opponent, but not if the player journeys to Tundaria Tower after having completed other dungeons.

Felling a Needle Egg yields 214 EXP (more than twice as much as the Urchin Beast), 110 coins, and in somewhat uncommon cases, an Antidote. Needle Eggs are battled in the snowy regions of Weyard’s south end, on the continent of Tundaria, as well as within Tundaria Tower itself.

Sea Hedgehog
The Sea Hedgehog is a small member with a dark purple body. The Sea Hedgehog has 177 HP, 402 Attack, 160 Defense, 188 Agility, and 8 Luck. It is resistant to Jupiter and highly succeptible to Mars attacks.

A Sea Hedgehog can attack with a physical attack and the monster skill Stun Sting, which does strong damage to a single Adept, may afflict that Adept with Stun, and visually resembles a series of long blue needles shoot from the enemy into the target adept. This monster, in spite of being a good deal tougher than its counterparts, is battled in the depths of Treasure Isle, where other monsters there outperform it in ferocity, and since Treasure Isle is explored very late in the game, this monster is not considered all that much of a menace.

Felling a Sea Hedgehog yields 319 EXP, 145 coins, and in uncommon cases, a Potion. Sea Hedgehogs are battled in the inner dungeon of Treasure Isle.
