"I do a little bit of rapping, a few skits, and I do opshop clothing fits as well. There's a couple of cooking videos every week as well.
Before the lunch challenge video, Willis-Croft has 136 followers on his TikTok page. That became 15,000 in a matter of days.
"I'm up to 51,000 followers now, so it's definitely up from where I was when this whole thing kicked off."
The lunch challenge has now been viewed more than 500,000 times on the social media platform and Willis Croft said Countdown Whanganui had "come through with $500 worth of vouchers" for him.
"I did a thank you video for them but it got blocked for some strange reason," Willis-Croft said.
"Apparently there was a 'community guidelines violation', but I wasn't nude or anything, it was just a thank you.
"My daughter is actually working there (Countdown) during her uni holidays, so she's more employed than me at the moment. It's really cool though, and it's her first 'job job'".
Despite the number of followers and "likes" (more than 1.5 million) his page and videos now had, Willis-Croft said making money from TikTok wasn't an option for those in New Zealand.
"I sort of stopped looking at my likes after it got over the million mark, because it makes me a bit sad. In the US people get paid by the TikTok Creative Fund on a 'per likes' basis but we don't have that over here.
"A million likes is enough to make living off apparently. You might think I'm in the wrong country, but there's no way I'd want to live in the US. I'm more interested in travelling around New Zealand than anywhere else.
"You can gifts when you do a live video, where people pay TikTok for coins use those coins to buy a present and send them to another TikTokker. I've made $120 in the four months that I've been doing lives. It's a slow process, but it's not really about the money."
The biggest TikTok stars had editors, Willis-Croft said, but he still did everything on his phone.
"I've got a real backwards way of working, but you just have to use what technology you have.
"The only real problem I've got is the fact that the microphone on my phone is really useless. The film quality is excellent though, and that's the main thing anyway, I guess."
Willis-Croft said he got recognised on the streets of Whanganui a lot more than he used to.
Dealing with internet trolls was another thing he had learned to deal with in 2020, Willis-Croft said.
"I get trolls on my live videos, and I just block or mute them. A lot of them will go and create a whole new account just so they can come back and speak again. I just repeat the process.
"There have been a few trolls who have become actual fans, so that's always handy. Now they'll probably just go and hassle someone else instead."
At present, Willis-Croft makes a lot of his content from his small cabin in Whanganui East, which sits in the front garden of his sister-in-law's house.
He'll be there for the next six months, and while it's incredibly small, Willis-Croft can still house himself and his two youngest sons when they come to stay.
"When I'm here by myself I sleep on the bottom bunk, and storage is on the top bunk. When the boys are here they have the bunks and I have a king stretcher on the floor. I have a hotplate and a rice cooker, and everything I need really.
"Hopefully I'll be having someone over for dinner on Friday too, so I'll get the foldout table up for that."
As for the future, Willis-Croft said he'd be interested in getting "some kind of hosting gig", or get paid to make content for television or websites.
"I'm pretty savvy with how to make videos, so I just need some backing to go fully crazy with them."
