I'm not sure if it goes the same spot each time but for me it went up between the railroad closet to dusty gulch and dusty gulch.
you use the lasso
go on google and type in,"Poptropica cheats for wild west island"
you have to get the cowgirls calf's first and then she'll give it to you
to find the calf on the poptroica's island Wild West Island you leave the town and look for hoof prints and follow them until you see the calf and then you need to click on the calf so the rope will get it then look on the mini map and take the calf back to the ranch! then go back to town and the lady will give you a used saddle !{which you can trade for a oil can or a gold mining pan}
Once you rope the runaway calf, lead it back to the corral just left of Rock Ridge. You cannot take it back into the town.
there is no 6 calf
you ride on the horse until you see the calf, and then you use the lasso and catch him.
the gold pan once you've used it
how can you find gold in wild-west island on poptropica.
follow the footprints from one of the stars
you follow the footprints near rockridge
unfortunately, you have to catch it again.
