Stack Them Up

Spoiler: Trick List

- auto pilot (tap the lift as R approaches, move lift to redirect B onto R)
- quick slide (slide the slider quickly to dismount a bot)
- auto pilot (tap the slider and move slider, when B lands on the rail, tap the grass)
- auto pilot (tap the grass, move the slider so B ends up on the slider)
- freeze bot (hold the lift to freeze a bot – required if another R mounts R)
- elevated eye (an elevated eye will change the properties of the block above to not passable)
- low ceiling zapper walk (B acts strangely when the ceiling is low, tap the stairs and B can walk over a zapper)

Spoiler: Behaviour

- B can walk onto R's back if R is bent over

Spoiler: Recovery Card

- This card starts you off at the last section – Z heading to the frozen spot

Spoiler: Video Solution

Found my way easily for the first 2/3 of the level but took three different gameplays before i got the finish. My path to get the second ball eas different.

Spoiler: Second ball

with B on the draggable performed a soft SSS to get beside the ball.

@ridgerunner - Yes, your 2nd ball method is good. I was thinking that SSS was blocked but not soft.... Thanks for P, C and R.
