Sticky metal?

Hello there. Thank you for your interest the "Sticky Metal Block" trick.

All you need are the following:
+ L or R Bot
+ Any metal blocks except rounded and rails.

Use metal blocks as their heads.this is just to show the mechanism.

 

All metal blocks are the same as long as it's not rounded and also the rail. Stickiness of the metal depends on B's leaning motion. If B leans on the metal block and you tap onto some places, B will stick on the metal block.
Note: B cannot perform the jumping action when you only tapped on a stair. You should tap two blocks(stair + one block that connects the stair).
You cannot put a stair too far away from the sticky metal block. Two blocks away is enough or else it will not work. B will tiptoe.
This trick is only 50% - 60% success rate if you executed correctly.
