Grub enemy line

The Grub (ウォーム Worm), Worm (スピアウォーム Spear Worm), and Acid Maggot (アシッドウォーム Acid Worm) are enemies that are randomly battled in Golden Sun. These monsters, resembling worms holding small spears, are palette swaps of each other that have differing levels of power and defense and are fought in different locations in the game.

Grub
A Grub is a light-green level 14 variant with a yellow underbelly. In Golden Sun it is battled only throughout Lamakan Desert.

The Grub is the easiest monster among the monsters it is fought alongside, enough to suggest that they are mainly meant as targets strictly for making the trip to Lamakan Desert a little less hard. The fact they attempt to flee makes battles involving them easy as well.

Worm
A Worm is a green level 18 variant with a light-blue underbelly. In Golden Sun it is battled only throughout Altmiller Cave.

The Worm is about the same as the Grub in respect to how its battling capability compares to the other monsters it is fought alongside with. It's a little more notable in that its ability to summon other monsters occurs rather often, literally half the time it is able to act, so it might be interesting to hold off on attacking for several turns and see how the enemy side doubles in size. Then use area-of-effect Psynergy to take out many at a time and get a pretty hefty EXP and coin reward.

Acid Maggot
An Acid Maggot is a violet level 22 variant with a light-green underbelly. In Golden Sun it is battled only throughout Suhalla Desert.

Once again, this monster is probably the least threatening of the random opponents in the area it can be fought in, complete with a small chance to attempt to flee. To its credit, it's certainly more capable of damage than its earlier counterparts.
