What does Mario jump on when he completes a level?

In the classic Super Mario video games, when Mario successfully completes a level, he typically jumps on a flagpole. The end of level flagpole is a common feature in many Super Mario games, especially in the side-scrolling platformers like the original Super Mario Bros. series.

Here's a typical scenario:

1. As Mario approaches the end of a level, he often encounters a flagpole located next to a castle or another iconic structure.
2. The player's goal is to time Mario's jump in such a way that he reaches the top of the flagpole.
3. When Mario successfully reaches the top of the flagpole, the level is considered complete.
4. A short jingle or fanfare plays, and Mario moves on to the next level or area.

This flagpole mechanic has become a classic and iconic element of the Super Mario series and is associated with the joyous feeling of completing a level. The height to which Mario reaches on the flagpole may also impact the player's score, adding an extra layer of challenge for those aiming for high scores. Keep in mind that specific details can vary across different Super Mario games and versions.
