[quote name='Razzuel']When I received the trophy I was at the minimum stretch length. I was not the small Boy where you are only the head and rear like when you first start the game. When you stretch at first Boy does not grow. At the point when he first grows from stretching is the minimum stretch length I am talking about. That is the length when I got the trophy.
Now the way I approached the trophy was to eat enough stuff to fill all of Boy's body at the minimum stretch length. Then I used L3 to reduce my size back to zero. Immediately after—if you do not do it immediately then the stuff still in Boy's rear will be ejected because he is not big enough to hold any more stuff—stretch back to that minimum stretch length. This way he still retains that stuff in his rear.
After stretching, eating, shrinking, and repeating that process for a while Boy's rear got to a decent size and I unlocked the trophy.
I hope that helps.[/quote]
Okay, I just got the trophy for it. What I did was stretch, eat till I start pooping stuff out, and hold L3. Rinse and repeat, and it took me half an hour to do it. Interestingly, Noby's body gets bigger overall everytime I'm back to normal, so I could naturally eat bigger objects from the start of every stretch I do.
And like you said, once you've gone back to normal, stretch immediately to keep all that stuff you've eaten from being ejected.
Thanks for the help guys. Now I've 100%'d this game as well...
