These lines mark the beginning of Garrett's obituary, words he spoke to his parents. He made up the surname “Boofias” because his real name was too hard for him to pronounce.
He expressed the things and people he loved, but also the things he hated, like pants, needles and "dirty, stupid cancer."
He was diagnosed with cancer nine months ago and died Friday, July 6, 2018.
"We never necessarily talked about his funeral, so we never had the conversation with him that he was going to die," his mother Emilie Matthias told CNN affiliate WHO. "But we had a lot of conversations around, 'When I die, I want to do this.'"
Garrett planned an imaginative funeral, with five bouncy houses (one for each year of his life), snow cones, and, of course, Batman.
"I want to be burned (like when Thor's Mommy died) and made into a tree so I can live in it when I'm a gorilla," he wrote.
"That's him speaking. Those are his words verbatim," his father, Ryan Matthias, told WHO. "When I read it, I'm just like, 'Wow.' Sounds like Garrett just yapping at me."
CNN was not able to reach Garrett's parents Thursday.
They said they will honor his wishes with a symbolic, Thor-influenced burial ceremony and fireworks on Saturday.
The things I love the most: Playing with my sister, my blue bunny, thrash metal, Legos, my daycare friends, Batman and when they put me to sleep before they access my port
Things I hate: Pants!, dirty stupid cancer, when they access my port, needles, and the monkey nose that smells like cherry farts…I do like the mint monkey nose like at Mayo Radiation and that one guy that helped me build Legos (Randy).
