Psuedo Rupee

Psuedo Rupees are quite bizarre creatures. They act and look like Like-Likes. However, no one can ever claim to have been damaged by these creatures. They will strike if you get too close, but only if you go for the rupee on their lures. They use this lure to bring in unsuspecting victims, then smother them and devour any rupees they have. If you can kill Psuedo Rupees, not only do you get your own Rupees returned to you, but you can claim the lure on their heads, too! These bizarre creatures have been nicknamed "walking treasure chests." But, then, do Like-Likes walk?

Pseudo Rupees will take a number of rupees from you corresponding to the value of their lure.
