Found 'em during my Ekoro play through a little while back.

First gives you underwater mobility in Sophia while out of water... Until you leave the ground. Stand in this pool of water to the left and then jump and Spark Tackle into the tunnel to the right. You'll be pushed up and out of the water without your state being properly changed, and you'll be moving at a snail's pace.

The second is in the same tunnel, and I have no idea how I did it. I was goofing around and jumping when suddenly I clipped into the ceiling. Didn't notice right away so I popped out... And then I accidentally did it again moments later and haven't been able to recreate it since. Yeah, no screenshot either...

Actually, I discovered the previous glitch while trying this one. There may be a connection, but if I did the water glitch the first time I clipped I certainly didn't notice.
