As a Pokémon expert with extensive knowledge of the franchise's mechanics and evolutions, I can provide you with an accurate answer to your question regarding Squirtle's move set.

English Answer:
In the main series Pokémon games, Squirtle, the Water-type Pokémon, does not naturally learn the move Dragon Pulse. Dragon Pulse is typically associated with Dragon-type Pokémon. However, through the use of TMs (Technical Machines) in some generations, Squirtle can learn Dragon Pulse if a compatible TM is available. It's important to note that the availability of TMs can vary between different games and generations.

Chinese Translation:
在主要系列的宝可梦游戏中，Squirtle（水属性宝可梦）并不会自然学会龙之波动这一招式。龙之波动通常与龙属性宝可梦相关联。然而，通过使用部分世代中的技能机器（Technical Machines，简称TM），如果有一个兼容的技能机器可用，Squirtle 可以学会龙之波动。需要注意的是，技能机器的可用性在不同的游戏和世代之间可能会有所不同。
