I remembered I encountered 2 hackers on Rainbow Road with Boo... lol I got 2nd but the barrage of Spiny Shells were hell. Even though I really hate hackers they're okay if they don't hack just to come in 1st all the time. Hackers in battle mode are just plain jerks.
I like playing with Hackers because sometimes their plan fails, they drop stars, pass fake thunder clouds that all the sudden disappears but you still get to have the speed for the entire race. But those hackers are just plain-out ridiculous
