For the ppl who want to make use of npcscan i am adding npc id too. But it's not really needed as the macro should be enough to make it work.
Make this into one macro:
/cleartarget
/tar Alpine Chipmunk
/tar Grotto Vole
/tar Oasis Moth
/tar Rattlesnake
/tar Rockchewer Whelk
/tar Sea Cucumber
/tar Yellow-
/tar Baradin Fox Kit
/tar Mac Frog
/tar Rock Viper
/tar Sassy Cat
/tar Wharf Rat
/tar Highlands Turkey
And click it when u get at the location. When you got your target then pls delete it from the macro or type the critter name your self as at couple locations there are 2 critters close to each other.
