You know I just realized something when Ash caught Palpitoad and unless something happens later on if he get's traded or something I don't know. Well anyways we all asked ourselves if he would of captured Archen which he didn't but what we should of ask was if he would capture Tirtouga I mean if there is a turtle around ash is going to capture it! But this ties into the problem mention earlier he already has two water types he doesn't need three. So I hope this theory to be correct so here it goes we now ash captured Palpitoad on a whim but what if wasn't just that maybe he plans to give to Shooti? I mean he wanted on and as a thanks for bringing up the Aqua jet problem he might give it to him, I mean it's a big if but it would work, and this leaves up open for a new water-type and since the pattern of Ash always capturing the Turtle (Squirtle, Torkoal, and Torterra). So opinions?
Ash catch turtles, with legs. He has not seen a tortoise. There is a difference between a turtle and a tortoise, that a tortoise lives in the sea, while a turtle can walk in land. I think the difference is not much, but it might be enough for him to not catch it.
