Ash and the rest of the trainers can seemingly pull out the correct Poke ball and know who it belongs to. The Pokeballs all look the same and have no tags or accessories on them for identification. It seems confusing as they aren't even looking and somehow know who it belongs to.
How does Ash and his friends know which Pokeball belong to which Pokemon without looking which Pokeball was pulled out and no accessories? Do they have telepathy?
