Rigby created an antidote to the potion. But Rishna and his assistant, Abdul, want to stop him from using it. After the villains kidnap Mark and Debbie, Tinker and Speedy come to their rescue, but not before the whole gang get into a little game of "Now you see me, now you don't" as the invisibility potion is passed all around.
