There are two commonly used sound effects used in two movies that I enjoy and want to have. The first is the metal pounding sound effect for whenever a Transformer in the Transformers Michael Bay movies is either being punched by another Transformer, or if one hits the ground hard.
The second is used when either ice or somekind of concrete or rock is breaking. It is used in the movie Ice Age mostly in this scene from the movie.
Another two metal pound sound effects from the Transformers Michael Bay movies that I want would be from this scene in Transformers (2007). The first one is when Megatron's transformation sequence into his Cybertronian Jet Form and the second one is when Megatron gets hit by Optimus Prime's blaster.
