The group ended up performing on the BGT stage with judge David Walliams after they impressed him with their sailor-themed song and dance routine.
Speaking about their possible performances at the Live Shows, the five-piece told Digital Spy: "We tend to have themes. When we extend the sailor theme, we'd have sailor-themed songs built around it like 'In the Navy' and 'Love Boat'.
"We do a little section that's around the theme and we have done themes like Harry Potter. It was a magical medley and Hermione turns into Superwoman at the end and we all sing 'Single Ladies'.
"There is a dance theme where do things like songs from Fame and we're all in Lycra. The Showbears in Lycra is not pretty!
"We should also do a Royal Family medley. That would be very camp!"
Explaining their act, the group said: "We are like a musical Monty Python. We think the Queen would love us. She'd love to see us sparkling. I'd hope she'd like it... If we don't win, we can go round her house and pinch all her clothes and jewellery."
Commenting on David Walliams's support for their act, they said: "I think David did us a huge favour getting on stage and that's the reason we got so much coverage. He was a real champion of us on his Twitter page and its lovely he's been so generous to us.
"It's great as well that he's not a gay icon like Paul O'Grady or Graham Norton. He's a straight comic and he just happens to love everything camp and outrageous. He's not happy unless he's running around in a dress. To have that support from someone like that means a lot to us.
"It's very flattering. Because he's a straight guy, he translates across the gap. He bridges the gap between the gay community and mainstream telly."
The Showbears added: "20 to 30 years ago you wouldn't have seen an act like ours on the telly. This sort of campery wouldn't have gone on. In our youth gay people were represented by John Inman and Larry Grayson, but now more celebrities have come out of the closet and people like David Walliams come out and say, 'Look I'm straight, but my partner I work with on TV shows with is gay and we're in frocks and we camp around'.
"For someone like him to do that allows acts like us to do what we do."
The group also claimed that after performing with Walliams in the first round that they are hoping to get Simon Cowell on stage with them for their next performance.
Britain's Got Talent airs this Saturday (April 21) at the slightly later time of 8.30pm on ITV1.
