RAT
[Behavior] Usually scurry randomly around in dark/dank places such as caves, dungeons, and swamps.

[Tactics] Simply slash them. Its as simple as that. If they crowd you, don't be shy to use the spin-slash.

[Tid-bits] In The Legend of Zelda: The Wind Waker, spread bate near their nests, and they'll sell you something handy.

ROPE
[Behavior] A Rope moves from one side of a room to another, always following a staight line, until it spots a threat and charges at that hoping to bash it to death.

[Tactics] Slash the Rope before it has a chance to run into you.

[Tidbits] Ropes received their name for their tendency to hang from ledges when sleeping, and having been stumbled upon by a rather unfortunate party of explorers whom were promptly bashed to death.
