toys don't have there effect listed before you take them and cereal that's only point is worth more you cant see how much its worth, also why do cereals have a times one next to them if you list every one separately no mater if duplicate?
Toys should have a tooltip explaining what they do both before you get them and after they spawn near your bowl, since you didn't see one I think it is a bug, I should check it out. As for the UI having the useless x1 quantity, it was a last minute change that cereals have a "persistent" state (some cereals getting new tags or accumulating value, like boats eating fishes and adding their value to themselves) and didn't have time to either find a way to group identical cereals or change the UI, since the game was made for the 7 days Brackeys jam.
