NM...I played the N64 version...doh I am an idiot!!!! All stuff below is null and void
it is impossible...it would take green turtle shells. Red turtle shells only come as 1. Green comes in 3 turtle shells as a shield. If he followed him off the landing off the one stage (not familiar with the name) he could successfully get the turtle shells in maybe a second or two. Get the green ones and shoot him out in under 6 seconds...but 4 seconds?? It doesnt seem possible, plus he used reds??? where are these facts coming from
Now, if he sat on the respawn of the items and with complete luck turned over 3 reds and fired them over and over very quickly I guess it is possible. However, a rule in our house was that you werent allowed to hit someone over and over, and had to give them a sporting chance. Obviously thats all out the window with most other people.
