From aibo version 3.00, you can check on your aibo's preferences that you haven't seen before.
Whether a food is liked or preferred is shown by the number of heart marks that appear for that food item in the Belongings screen.
Also, you can check aibo's preferences for foods in the following ways:
- The tricks that aibo does
- The state of aibo in the My aibo app
- The AR view in the My aibo app
