During a Team Rally all races and battles become Team Games so the effects of some items change slightly.
Item effects are as follows during a Team Rally.
Note: If you play multiplayer with Team Rally rules, please see "How do items work in Team Games in multiplayer?"
■ Races
・ Lightning and Blooper
Does not hit teammates
・ Spiny Shell
Targets the racer in 1st place among opponents
Note: It does not target teammates.
・ Red Shell, Bowser's Shell, Yoshi's Egg, and Birdo's Egg
If a player throws one, it will target both teammates and opponents, but if a computer-controlled driver on your team throws one, it will no longer target teammates
Note: They may hit teammates who are in the way of where they're traveling.
