Buana Kima squeezed himself into the entrance to the cave.
He pulled at the rocks which held on to Buana Kifaru's foot.
He pushed and pulled at the rocks with all of his might.
He tugged and shoved the rocks, one by one.
Little by little the rocks started to move.
Finally, finally, the rocks moved enough to free Buana Kifaru's foot.
Buana Kifaru pulled his foot out of the cave.
Then Buana Kima pulled the ball out of the cave.
