You can't catch it. You have to have someone trade you a polliwhirl with a kings rock and then you'll have a politoad I found a kings rock on one of the sevii islands..I forgot which one tho I hope this helped you though
you cannot.
By trading and catching them i think
Use a gameshark code that is the only way
you can migrate it from firered and get one then get the egg of it hatch it and done to evolve it by water stone or
get poliwherl and use water stone. Hint: YOU CAN NOT GET POLITOAD IN THIS MANNER! IF YOU WANT HIM I THINK YOU GIVE POLIWHERL A LEAF STONE!
You can't catch it on Firered you can only catch it in Emerald
You can't catch it.
you can not catch him
You can catch a Ho-Oh at Navel Rock in Pokemon FireRed.
You can catch Moltres at Mt. Ember Peak in FireRed.
You cannot catch one but you can make one by giving a poliwhirl a kings stone and trading it back and forth.You migrate him from the GBA games.
