Well, to start this off, I am trying to look for certain patterns.
I can only assume that only 4 presents are the bad ones as otherwise if there were 5, there would be danger.
There are 4 red boxes. Nice, Cool, Silly, Lame.
4 boxes without any dots. Nice, Cool, Bad, Good.
4 boxes with the same amount of vowel and consonants. Nice, Cool, Good, Lame.
I think that Classic might be a safe bet along with Smart. IDK though.
