Feraligatr learns the moves double head hit, sonic boom boom and slap attack with lightening.
He can learn all the same moves from leveling up as feraligatr and totodile, excpet there he learns some different tms from them
Feraligatr cannot learn Sheer Cold.
Level 58 will feraligatr learn it
You go to Blackthorn City and you go to the move tutor house there and then you talk to the man and he teaches your Feraligatr Hydro Canon. You can also learn the moves Frenzy Plant and Blast Burn from that man.
my moveset for Feraligatr was crunch ice fang superpower surf I'd prefer waterfall rather than surf for feraligatr but I don't know why i didn't do that, i had that moveset when i was battling the elite four in soul silver it helps you against Will, Karen and, Lance. If you want you can change some of the moves. Feraligatr learn all of those moves by leveling up except for surf which is an HM
feraligatr learns hydro cannon at level 74
Feraligatr cannot learn Ice Punch naturally however a Move Tutor can teach Feraligatr Ice Punch in "Pokémon Platinum," "Pokémon HeartGold" and "Pokémon SoulSilver."
Waterfall is an HM, so Feraligatr doesn't learn it by leveling up. If you have the Waterfall HM, it can be taught at any level.
Feraligatr cannot learn Waterfall in Pokémon Gold and Silver, additionally it cannot be taught it via the HM.
feraligatr only learns like 5 or 6 moves plus the option of hydro cannon so im going to tell you all the moves through out the day you get/got tododile to the day you get a lv 100 feraligatr. feraligatr starts with 2 moves scratch & leer then he learns water gun,rage, bite, scary face, flail,agility,crunch,slash,screech,thrash,aqua tail,superpower,and lastly hydro pump.somewhere in there he learns ice fang but i don't know when since i kept it forever bonus:once you get to blackthorn city there is a house on the left of the Pokemon cednter it will have four people talk to the old man on the right he will ask you if you want an ultimate move (for feraligatr) tap yes and he will teach your feraligatr hydro cannon p.s. i don't know the levels
No, the last move it learns on its own is on Level 71. You can still make Feraligatr learn a TM or HM move however.
