Chikorita:
Every autumn, Chikorita and their evolution changes color, so it's rare to see one with an orange leaf. Along with Bayleef and Meganium
The dark green buds around their neck can sometimes fall off, this doesn't bother them however. The buds can sometimes harm a passing trainer if stepped on.
They would also use the leaf on its head as a disguise so they can hide from their predators, it could also be used as a weapon.
Cyndaquil:
Whenever a Cyndaquil is born, the four red spots on their back would usually start off to be a little painful like a headache but once the Cyndaquil gets control over their fire, the pain goes away.
They can also open their eyes but choose not to, so it is rare to one with their eyes open. They would also sometimes open their eyes if they are startled.
Whenever a Cyndaquil isn’t fully trained yet and is in serious danger, they set their back on fire. They would also use this technique to alert their guardian or as a way to communicate to other Cyndaquil far away.
Totodile:
Although they are playful, they could sometimes injure their trainer by accident through a bite. The bite isn’t too painless, but it's like the equivalent of a child biting.
Whenever a baby Totodile’s teeth start to grow, they use a rock as a teething toy but sometimes their trainer’s arm.
Totodile would often sleep with their mouths open sometimes, this would result in them accidentally biting their trainer’s hand if awakened.
