Eevee into Vaporeon. Really good Pokemon.
By getting a water type Pokemon & teaching it surf
you can obtain a water type by getting totodile as your'e starter or you can fish or surf in the water
Flannery is not hard if you have a decent rock type, water type or ground type Pokemon with you simply use that Pokemon throughout the fight.
In Pokemon Silver you can find Wooper in Route 32 but only at night and you can also find it in the Ruins of Alpha in both the grass and in the water but water-wise only via Surfing on a Pokemon and in the Union Cave you can find it in the cave as well as by surfing on the water.

Water objects draw out certain Pokemon from the safari zone. They are: puddle, fountain and water hole.
Yes, there are decent Pokemon that can't learn earthquake. Each Pokemon has its own strengths and weaknesses.
To get one you have to give a water stone to a Poliwhirl.
