What level does Squirtle learn bubble beam?
It doesn`t learn that move in any Pokemon games :(
At level 22 in Diamond and Pearl and level 18 in Platinum/HeartGold/SoulSilver. However, if you evolve it into Prinplup first, it is at level 24 for Diamond and Pearl and level 19 for Platinum/HeartGold/SoulSilver. Also, there's no reason to use a TM for Bubble Beam when you can teach it much more powerful attacks like Surf later on.
Bellossom cannot learn Petal Dance or Solar Beam via level up in DPPTHGSS. However, Bellossom can learn Solar Beam through TM. Gloom learns Petal Dance at level 53, so if you let it learn Solar Beam, then evolve it. In RSEFRLG, Bellossom will learn both Petal Dance and Solar Beam. Petal Dance at level 44 and Solar Beam at level 55.
The moves that Lanturn are capable of learning through level-up in PokÃ©mon Omega Ruby and PokÃ©mon Alpha Sapphire are Thunderwave, Supersonic, Eerie Impulse, Bubble, Electro Ball, Confuse Ray, Water Gun, Bubble Beam, Spark, Swallow, Stockpile, Spit Up, Signal Beam, Flail, Take Down at Level 43, Discharge at Level 37, Aqua Ring at Level 47, Hydro Pump at Level 51, Ion Deluge at Level 54 and Charge at Level 58.
