how to retrieve things stuck behind zoo gate

If you have something stuck behind a zoo gate, go into storage mode. You need to put the island in larger view. If you keep it in small view the gate will not reach to the lower right corner. Slide your island to the lower right corner and adjust until your gate hits the lower right corner. The gate will disappear in the one exact spot and you can often reach and grab what is behind the gate. I got several things rescued that way. This was discovered by a genius zoo friend.
