You can catch Psyduck pretty much anywhere up to snowpoint city
Psyduck can be caught in most water areas in FireRed, but is not availble in LeafGreen
North of Vermilion city is lake surf on it and eventualy you will encounter Psyduck.
for me the best Pokemon you can catch with the good rod is carnavina.the rest are magicarp,goldeen and psyduck(psyduck is found in the safari zone)
Hypno's Naptime
You can find psyducks at Seafoam Island
Well You catch Magikarp, Goldeen, Finneon, Psyduck.
You have to catch a Psyduck, then train it to level 33. Or you can catch one in the Safari Zone, but it's really hard to get them them wild.
you cant catch it at Solaceon town but you can catch it on the west route of hearthome city
magickarp goldeen psyduck hope this helps :)
Just capture a psyduck in the great marsh and just level it up until it evolves
Go to Safari Zone. In the spot of water, capture a psyduck. Evolved it.
First of all it depends on what route your fishing in but you catch these pokemon: Magikarp, Staryu, Carvanha, Horsea, Psyduck, Goldeen.
