Well if you are standing at the temple door and the sim is shacking its head and a bobble
comes up with a rectangle thingy in it then you haven't found all the holographic pieces.

If so here are the places to find them:
Deep jungle - near shipwreck lagoon portal,where the path splits
Pier beach - beside ancient pier
Shipwreck lagoon - on ship to the left of the ramp
Dark cave - to the left of the llama crown door
Skull rock jungle - to the left of the skull rock
East river plains - left of the two pilars(opening) that you can't cross
South river jungle - far left side of shoreline behind some stones
Volcano jungle - to the right of the upper hot spring
Geyser plains - to the right of the llama temple door

But if you are in geyser plains and are at the spot where the steam is rising from the
rocks that's a completely different situation. If you look closely, to the right of the
steam spot there is a little path that rises up a little ways. At the top of the path
there is a large bolder. You have to be in just the right spot and then you'll see a
little action thingy come up and it will say chisel rock. Click it and your sim will start
to chisel at the rock until it comes lose, falls and covers the large hole your sim could
not pass before.
Hope this helps and please ask me to go into further detail if this doesn't come clear to
you!!!
