I took a look at your program and I added an instance variable to your object and an event to move and display text when that object is tapped. Since your example has a filled slot animation rather than moving the item, this only works when the item is clicked before it's moved. Since you chose to use the "touch" feature, there is no "mouseover" event and I made the event to act in a manner appropriate to a touch interface.
However, I want to make some big recommendations on to how you're handling this:
* Make your apples and pears separate objects. You can add them to a family so you can change your events so when the player collides with a member of the family it picks them up.
* Rather than have a separate sprite for a box with an apple or pear in it, move the object to the box. This simplifies a lot of the events, removes the need for most of the instance variables, and simplifies the need for assets. This way you'll only need 2 sprites for the box (empty and the highlighted one) and you could use an arbitrary number of objects as pickups.
