The only reason I can think is that the Blooper affects only the people in front of you, so basically if you are in a lower position, you affect more people.In the Mario Kart games, a blooper, one of the most useless items, can be obtained in the same position as a bullet bill, golden mushroom, or basically any other useful item (as low as 9th in Wii, 6th in 7 and idk about 8/8DX) How do they think that a blooper is as useful as any of those items?
Thank you for reading.
