As a Pokémon expert, I can tell you that Smeargle is a unique Pokémon known for its ability to learn almost any move through the use of a move called Sketch. However, the level at which Smeargle learns Sketch can vary depending on the game version you are playing.

In the main series games, Smeargle typically learns Sketch at a higher level. For example, in Generation I (Red, Blue, and Yellow), Smeargle learns Sketch at level 42. In Generation II (Gold, Silver, and Crystal), it learns Sketch at level 40. The level at which it learns Sketch has been adjusted in subsequent generations, and it's important to check the specific Pokédex entry for the game you are playing to get the accurate level.

Remember that Smeargle will learn Sketch every 10 levels (starting at level 1), and it can't know Sketch twice, so make sure you use the current Sketch before levelling up. The Move Relearner can also re-teach Sketch for the cost of a Heart Scale.read more >>
