Gumball gay

As early as Season 1, & as late as Gumball Chronicles, Leslie has been shown to be gay all throughout the series. Some quotes/actions? Talking about boys with the girls in The Pressure & literally confessing on screen that he made up his boyfriend, I believe his exact quote is “yeah, I made him up too”.

Aside from there being a lot of hints and jokes about it in the show, Ben Bocquelet made a tweet at one point implying that Gumball is mspec. Now I’ve seen a lot of people claiming he is “canonically bi” or “canonically pan”, but is there anything else that would support one of those?.
