Parrots will be useful: item picking/dropping

parrots imitate sounds than-->
why not make them also imitate the getting and dropping of an item?

-It would be an incentive to have parrots
-would make the sorting of items more viable

a new item is needed: the roost where the parrot can reside

Training mechanics:
1- the parrot is on the shoulder of the player
2- the player clicks on the roost, the parrot positions himself and memorize that roost
3-the player collects an item;
 the parrot learns the item picked up by the player
4-the player drops the same item;
the parrot memorizes the Spot where the item is dropped
5-the parrot from now, collect that kind of item and let it fall into the learned Spot
6-if there are no items to collect, he positions himself on the roast

7-to remove an item from the parrot's memory:
8-the player puts the parrot on his shoulder
9-player collects the item from the ground

I let you imagine the combinations with droppers and hoppers ;)

in the memory of the parrot will be saved rows like this:
roost; item; DropSpot

upon removal of the roost,
the enuples containing that roost are eliminated
