It took me about 20 minutes to train all three of my piggies to climb the ramp. I rumpled a plastic bag and got the guinea pigs excited about veggies, I put the veggies on the second level. Next I took one small piece of lettuce and led the first one (Sir Robin) up the ramp, he got it in the first try. The other two guinea pigs ran around in circles wheeking looking for the lettuce. I continued trying to lead the other guinea pigs up the ramp over and over again. After awhile I left a piece of lettuce almost at the top of the ramp. They knew it was up there but were just too nervous about going up the ramp. Eddy Pig eventually figured it out that way and started going up and down the ramp right after that. Ben however just couldn't figure it out. I had to pick him up and put him on the ramp then push his Benny Butt up to the top. Once he was up there you could just see it in his face, it clicked. Anyway that is how I did it. =D
