Well I have a few questions:
How do I get a wailord, like what rod do I need to catch it?
Were do I get the rod to catch Wailord?
What route is Relicanth found on?

And I bred a Ludicolo with a Swampert to get a egg that hatches into a mew (a hint I found) and I had the egg for 2 days. I was going up and down a sandy slope for the whole 2 days (you know, so I could move to get the egg to hatch) and I was still playing it its only says 'Its moves ocasionally it should hatch soon. Any hints on how to make it get to the last stage then hatch? Will it really be a Mew?

Relicanth is found underwater
For the Mew, what sort of hint is it? Did you use a cheat code? Breeding Ludicolo with Swampert should give you a Lotad or Mudkip.
When the egg says "It moves occasionally", that means that it needs less than 2560 steps to hatch...keep walking

thanks. aboutthe mew thing. There was no Gameshark involed =) It just said to bred a female ludicolo with a male swampert to get either a mewtwo or a mew. I got lotad.

and thats all you will ever get!!!! unfortunately people make stuff up like that. some are even quite detailed like the rumours about the rocket going up to space and you get to catch deoxys or jirachi (also false).

you can find info about relicanth here:

and wailord here:

although wailords can be found in the wild, they are super rare (only 1% appearence rate). so youre much better off catching a wailmer which can be found almost everywhere:

the downside is youll have to wait until its level 40 before it will evolve into a wailord. but if you want your regi's, you wont mind putting in a bit of hard work right!!
