From Inkipedia, the Splatoon wiki
- Not to be confused with conch shells.
Festival shells are an item in Splatoon 3. They increase the odds of getting into a 100× or 333× battle during a Splatfest.
When a player wins a 10× battle during a Splatfest, they earn a festival shell.
When multiple players on a team hold a lot of festival shells, the chances of getting into a 100× battle are increased. If both teams in a match each trigger a 100× battle, a rare 333× battle occurs instead. After a 100× or 333× battle happens, the players involved have their festival shells disappear.
|“||Winning a 10x Battle also earns everyone on your team a festival shell. And if you team up with other players with lots of festival shells, the odds of triggering a 100x Battle increase! What happens if both teams trigger a 100x Battle at the same time? An ultra-rare 333x Battle!
Now, if you play in a 100x or a 333x Battle, you'll lose all your festival shells. But isn't it worth it for a chance at all that Clout? (Trust us - it is.)
