The 21-year-old cereal addict has named his challenge 'cereal quest' and plans to give each different brand an individual score.
Morrison tweeted: "Think I'm going to go with a overall scoring system of 1-5 'spoons' 1 being worst ovvi! 5 being best! Also with an evaluation #Cerealquest."
The centre-back recently claimed that it is his aim to inform the public of the best brand of cereal.
