A warning about quicksand: if you run in it, you sink. If you walk into the middle of it, you sink.

The Psychic near the quicksand has a Sigilyph Lv. 24. On the opposite side is a Psychic with two Pokemon: a Woobat Lv. 23 and a Muuna Lv. 23. If you fall through the quicksand you'll find a Revive. Past the third quicksand is a person who will give you either a Cover Fossil or a Plume Fossil. When resurrected at the Nacrene Museum, the Cover Fossil will give you a Tirtouga, while the Plume Fossil will give you an Archen. Choose wisely! That's all for now. Don't worry though--you'll get to come back later. For now, go to Nimbasa City.
