Wrong
Dude you got the script in this movie wrong the name is right but goku and vegeta arent in training there on a distant planet where frieza,coola,and king cold lived and coola was rebuilt in a robotic form and after goku and vegeta beat him over a hill theres like a million more robots just like the one they defeated and thats how it really goes i dont know if you misunderstood it or like heard it as a rumor from someone but i know since at a website the maker of Db and DBZ allowed this website to view his log then in it he explained certain scripts of the movies and this is one of them i just wanted to tell you fully and i own it on dvd i bought it from china...just saying
