I think it's between the dark room and the pit if thats what you mean.
It is Shark Tooth Island after Early Poptropica Island.
Do not go into the tunnel left of the Spider Cave unless you have the Glow Stick from the well in Early Poptropica village.

You don't actually find the crooks, you just find the things they stole. But, the first stolen item is in the second underground tunnel.

There is a glow stick in the well in Early Poptropica village. Go down to the bottom and climb to the upper left. If you use it in the Spider Sewer, you can go directly left into the tunnel to find the Golden Egg.
It is in the clouds on the island of Early Poptropica.
