"While they might not look very challenging, they like to stick together in groups. If you find yourself against many of these bugs, use Flint's Swing skill to take them all out together. Drops Running Bomb (10%)." - The Mother 3 Guidebook
"These gather in groups to protect themselves from enemies. They'll proudly attack anything that appears to be weaker." - Battle Memory

Spud Bugs are enemies in Mother 3. They can be found in the upper part of Sunshine Forest in Chapter 1, before being replaced by Big Spud Bugs in Chapter 4. They often attack in groups, but are slow moving on the overworld so battles can be avoided easily. They have a small chance of dropping a Running Bomb.

Its battle sound is Battle Sound 29, a battle sound used exclusively by Spud Bugs and roaches, which falls under Code Numbers 523 for regular attack, 524 for Smaaaash! and 525 for Miss.
