Sheep macro help

Hey I’m trying to make a sheep macro. Pretty simple.

#showtooltip polymorph
/Stopcasting
/Cast polymorph
/S sheeping %t

I wanna make it so it doesn’t spam “sheeping %t” everytime I click the keybind i have it on. So it doesn’t spam when I have to re-sheep or w/e

Also I’d like to add a moon Marker but I forgot the command.
And maybe add a random funny message said randomly.
