What Pokemon do I use to get through the small holes in Shoal cave in ORAS?

Question

There are small holes in Shoal cave that are "in" water, so obviously I have to surf to get in there, but my surfer won't fit. What Pokemon is small enough to get through there? Also, what's behind there?

Comments

Small indents in the wall need Secret Power, holes underwater need a low tide. But then again I've never gone through shoal cave yet so I don't know what other holes there could be :L

Answer 1

Shoal Cave is unique in the way that it changes with the tides. These inaccessible caves can only be entered during a low tide. Inversely, some parts can only be accessed during a high tide. The tides change during certain times of day.

High Tide: 9:00 pm - 2:00 am & 9:00 am - 2:00 pm

Low Tide: 3:00 am - 8:00 am & 3:00 pm - 8:00 pm

Answer 2

You need to go to the shoal cave at ''low tide'' which is from 3 am to 9 am to 3 pm to 9 pm. Then there will be no water. Also, shoal shells and shoal salts can be found behind there. There is also a secret bright icy part where you will find the tm for hail and the glailetite (not sure if I spelled it right). Then there is the high tide (that's the one with water!) which is from 3 pm to 9 pm.
