- "Three years later, the Spud Bug is now a respectable adult. But what does that even mean for a bug?"
- — Battle Memory
Big Spud Bugs are enemies in Mother 3. They can be found in the upper part of Sunshine Forest from Chapter 4 onwards, and are grown-up versions of the Spud Bugs from previous chapters. They have a small chance of dropping a Sprinting 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.
