Urchin Beast enemy line

The Urchin Beast, Needle Egg, and Sea Hedgehog are enemies that are randomly battled in Golden Sun: The Lost Age. These monsters, resembling very spiky sea urchins with two wide-open eyes, are palette swaps of each other that have differing levels of power and defense and are fought in different locations in the game.

Urchin Beast
An Urchin Beast (ウニビースト Unibisu, lit. Sea Urchin Beast) is a violet level 21 variant. Urchin Beasts are battled all throughout the Great Eastern Sea as random battles while sailing on the Lemurian Ship.

The Urchin Beast has the lowest HP of the monsters in the Great Eastern Sea, its attack falls quite short of the Merman's attack, and its agility is outsped by the Seabird. It having the highest Defense does not compensate enough to make it that much of a threat in random battles.

An Urchin Beast's statistics are as follows:

An Urchin Beast uses the following battle commands with :

Needle Egg
A Needle Egg (ニードルエグ) is a bright yellow level 28 variant. 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.

This monster can be fought almost right after getting access to the Urchin Beast, since the continent of Tundaria is accessible as soon as you access the Great Eastern Sea, which makes it worth noting that its statistics are quite a lot higher than its predecessor. Of course, you would have had to complete Aqua Rock first and gotten its Parch Psynergy in order to properly complete Tundaria Tower, so by then you'd be appropriately stronger. The Needle Egg has the lowest HP but the highest Defense rating of the monsters fought on Tundaria, its offense is beaten out by the Dinox, and its agility is beaten out by the Squirrelfang.

A Needle Egg's statistics are as follows:

Sea Hedgehog
A Sea Hedgehog (シーへッジホッグ) is a dark purple level 36 variant. Sea Hedgehogs are battled in the inner dungeon of Treasure Isle.

Each of the Sea Hedgehog's statistics are outperformed by at least one of the other monsters fought randomly in Treasure Isle. As usual, it has the lowest HP rating by quite a large margin, its attack is most outperformed by the Ocean Dragon, its Agility is lower than that of the Great Seagull, and even its Defense is not the highest in the area, being outperformed there by the Puppet Warrior.
