she would need a point of respawn, like the Splatoon 3 spawners, and she would preform a Squid Spawn into the lobby. But a Squid Spawn makes noise, so if she gets Splatted at night, Meggy respawning would wake people up with:
Her ghost being retrieved by the Spawner and her body reforming from the little ink pool
The Spawner shooting her out
Squid Spawns give the player a shorter Splatoon 2 Ink Armor that tanks 100.0 damage, but overflow (damage dealt is greater than the 100.0 HP of the armor) will splash onto her. A 130.9 attack will overflow and she will take 30.9 Splash Damage. It does only last I think 3 seconds
