So, a rock gets pushed off the board. There's an elephant directly behind the rock, but he's facing sideways--so he doesn't get credit for pushing the rock off the board. Directly behind the sideways elephant there is a rhino facing toward the rock. There's another elephant behind the rhino facing toward the rock who is the initiator of the push.
Does the rhino get credit for pushing the rock off?
--and--while I'm at it:
if there are two rhinos facing a rock, can the rock be pushed two spaces?
The Rhino would win in that example. This situations comes up often and works a good defensive strategy.
Rock can be pushed one space.
