Despite having different effects and inventory icons, when dropped on the ground, Lesser Glowberries use the same assets as normal Glowberries.
Apparently, this is because their constructor function does not use the bank/build arguments passed to it, but explicitly uses the normal Glowberry assets instead. (This was reported by someone else over a month ago and got buried, so I only recall the broad strokes of it.)
1. Drop Glowberry on the floor.
2. Drop Lesser Glowberry on the floor.
3. They're the same picture.
