Sorting Some Shapes

This is Finley's favourite and most hated toy. He loves sorting shapes but he also gets super annoyed with this toy. It does lots of stuff and I think he gets confused. Basically you put all the shapes in then press the button in the top to release them. But it doesn't always work, sometimes it plays a song, sometimes it makes a grinding noise and does nothing, other times Finley throws it across the room an screams.. I think it is time we looked for a simpler shape sorter.
