The twins, pictured at Dublin airport as they travelled to Germany, will represent Ireland in the annual competition with their track 'Lipstick'. They will perform in the second semi-final next Thursday, hoping to secure a place in Saturday's final.
Discussing their performance plans, John Grimes told What's On TV: "The song has a lot of attitude, so we won't just be standing there singing it, we've got to get into the zone.
"We'll be running around a lot backstage, but when it finally happens we'll be like, 'Let's make this amazing'. We don't want to be nervous, we just want to enjoy it. We're gonna own the show!"
He continued: "Right now, it's all about getting to the semi-final. But if we do get through to the final, we'll definitely make our routine bigger. Everyone will remember our performance!"
Asked if they were disappointed that fans in the UK will not be able to support them in the semi-final, Edward said: "We think our fans in different countries will vote for us. There's a lot of depressing music around at the moment, and our song will lift the whole competition to a new level."
It was recently claimed that Eurovision bosses had stopped the duo from featuring two tigers in their performance.
The Eurovision Song Contest, in which the UK will be represented by Blue, takes place in Düsseldorf on May 14.
