Piggyback Skip

Piggyback skip is a skip performed in Lost Precursor City. It is performed by high jumping on top of a Double Lurker and then high jumping again to get over the wall collision, allowing Jak to collect the "Climb the Slide Tube" power cell earlier than intended. It's called Piggyback Skip because the Double Lurker looks like it is piggybacking Jak when Jak jumps onto it.
