- This script automatically; Collect stones,Claim mystery gifts,Claim collectible gift,Adopts animals,Get buildable items,Get topiaries,Help animals,Help friends,Heal animals,Feed animals,Find animals, Lend hands

# Use the latest stable browser version of your kind.Mozilla Firefox supported and tested
# Use the url cleaner script for best results
