Me - I wear a hat and stand at the head of the sloth for safety. My goodness if they can spit snails, I'm sure they can fart bullets. Just a friendly safety message :)
The best way to feed sloths is to find two fairly close together. Knock on the first and feed it a rod. Then run to the other, knock and feed HIM a rod. Run back to the first. Any snails you were too far away to get will be on the ground. Feed him a rod right away and then pick up the snails. Now run back to the 2nd, who will be finished with his rod. Feed him another rod and pick up any snails. Keep doing this until they are full. it is important to feed each sloth as soon as possible because they will otherwise lose interest and retreat to their tree. Following this technique gets you twice the snails in the same amount of time as feeding one and keeps you from losing your mind with boredom.
Walruz, you can do that without all the running. Just stand in the middle. feed the sloths by dragging rods from your inventory and pick up the snails with your mouse.
Incorrect two sloth people ;) The best way to get snails is to go to Gomed Essoni, the only sloth street in the game with four sloths close enough together to feed all four at once!
The crazy hoppy jumpy process of keeping 4 sloths munching on rods until they're full is incredibly active and fun. It yields over 250 snails per round, so I got my 10k snails from sloths badge with relative ease!
Try it out, it IS pretty tough, and report back here with your results ;)
I dunno when you've been there, but they're never full for me :) I did nearly every single one of my 10,000 slothy snails in Gomed Essoni. Perhaps I was the one who was always making the sloths full before you arrived ;)
I like using the /zoom setting to be able to pick up the snails from farther away if I'm standing in one place in the middle and don't feel like jumping around. Kind of the lazy man's sloth feeding. Usually /zoom .6 or .7 is good.
