Shooting Star (item)
From the Super Mario Wiki
It first appears in Paper Mario, where it is very valuable and somewhat rare. It deals six damage to all opponents in the form of showering them with shooting stars; the only enemy who is immune to this item is Monstar. One can be obtained by talking to a Hammer Bro during the Chapter 6 Intermission at the leftmost point of the library while Princess Peach is disguised using the Sneaky Parasol, which she can put in the mysterious treasure chest for Mario to collect later.
This item reappears in Paper Mario: The Thousand-Year Door. The item's description claims that the Shooting Star has a chance of causing Confusion, but this is false. This item can also be cooked by mixing a Thunder Rage with a Point Swap. It can be cooked with a Shroom Fry to produce a Meteor Meal.
When used in Super Paper Mario, players have to aim the remote at the screen and fire at all the stars that appear. The attack grows in strength in proportion to the amount of stars hit. A single Shooting Star can be cooked to make a Meteor Meal, which has the same effect but automatically does the maximum amount of damage without an action command, making it a straight upgrade. One can be found in Outer Limits inside a brick block, another can be found in The Overthere in Sector 5, and enemies such as Fotons and Hogarithms drop them on occasion.
