Heh, that's because the reflection IS from hedgehog.

Basically, water reflection in RO maps is a bit of trickery. You take pictures of the level from the point of view of the water and set it up so that anyone looking at the water sees reflections of these pictures.

This is called a cubemap, and here's a short overview from the UDN: http://udn.epicgames.com/Two/MaterialsEnvironmentMaps

Yes.
You can also use this EnvMap in a combiner with other textures (for example glass) so can achieve even more realistic water.
