Good job! I suppose that Tarakotchi likes Shrimp - like in V2. Oh well, some likes and dislikes are different in V2...
There are no shrimps on V3, so it's not shrimp.
and 'Fluffy Snowman' Georgia-Kate tried Hikotchi on cherries- it's not them
I tried Bill on fish- it's not them. It has to be an item that will make them jump up and turn around and fill empty hearts AFTER they have eaten it (not just before).
So that's why they are not on the chart.
Have you got any of those characters on your list at the moment you can double check with as there is an awful lot of fish there!
