Hulk has changed the way his diary looked because Hulk got a lot of emails about his diary looking "ugly" and people don't realize that Hulk is not that good at design and internet stuff so he talked to his friend that helps him put up his diary and told him that he would not smash him if his friend helped him redesign the diary so it is redesigned now!
Hulk may need to "tweak" a few things, but Hulk thinks that it looks MIGHTY SNAZZY NOW!
