Bulbasaur don’t belong to any one habitat — the energy inside their plant bulbs lets them wander far from their birthplace without a steady food supply. This also means they’re not easy to train with treats.

Bulbasaur becomes territorial as an Ivysaur, coinciding with the bud growing heavier. The unfurled leaves compensate with increased photosynthesis, so Ivysaur clearly mark and are very protective of their favorite sunning spots.

Venusaur’s bulk requires lots of energy to move, so it prefers absorbing sunlight and only luring prey for nutrition. A lack of sun makes them aggressive, but regular feeding makes for docile big ol’ lugs.
