Butterfly analysis
Butterfly is the most strategically important pet in the game and its value has nothing to do with its weight. It converts environmental mutations into the Rainbow growth tier (×50), which is the single hardest multiplier to obtain naturally at roughly a 0.1% chance. Effectively it turns mutations you already have into the growth tier you cannot farm. Every other pet on this list competes on multiplier size; Butterfly competes on access.
