Use either the toastbot or the toast shot by toastbot to get OoB and reach the end.
Toastbot method (slower but easier)
Turn around as soon as you're able to move.
Get close enough to the toaster, so it starts chasing you.
Start moving towards the wall as soon as the toaster starts turning from side to side (usually after the third shot).
Stand next to the wall as shown in the video (it's important to be a bit to the left of the red line) and turn the camera around. Move towards the wall in order to prevent bouncing too far to the side.
After the puppy is clamped near the wall, start gently tapping left or right to turn around, so the toaster is in front of the puppy. Make sure that the camera went completely OoB (down) and then clip into the void.
