Enable free play
Just successfully complete all of the training missions (every icon has three things under it) to unlock free play in arcade mode.

Go to Training Mode to unlock these.
These won't work on the first try because you need to complete them on level 3.
(level 3 is when there are two solid symbols under the picture of the mission and one transparent symbol) Then you will unlock the item. All of these items will go either to your inventory or the shop in special mode.
I'll put Shop or Inv. to confirm which one they go to.
