How to get the trophy Shellcreepers trophy?

Answer 1

The Shellcreeper is the first enemy to appear in the Super Mario Brothers game. They walk out of the Warp Pipes at the top of the screen and walk towards the pipes at the bottom of the screen. The player must hit it from below to flip it over and run into it to defeat it. If the player does not run into it, the Shellcreeper jumps out of its shell (revealing that it wears a white shirt and shorts), flips its shell over, changes color from green to purple, and continues moving faster than before. If it flips its shell again, it will turn red, its fastest state.

There is no trophy in the game called the Shellcreeper Trophy.
