How about making a way where if you have multiple pets out, you can shrink them all at the same time. The reason I suggest this, is that I use wool from sheep to make cloth, and it is very annoying having to shrink each individual sheep one by one. Also, before anyone says "Oh well why don't you just buy the cloth?" the answer is because I like to make my own. Not quite sure how many people on here do the same, but it would also work for other reasons as well.
Each 'shrink' requires a potion (or just 1 if using the everlasting).
Other than that, I could only see it be implemented via command " [shrinkall ", such that it automatically shrinks each pet within normal shrinking range one at a time, using a potion each pet and stopping when no pets in range are found or if the user runs out of potions.
:mrgreen: Good? Lets suggest that? :geek:
