John Hornby Skewes & Co will be extending its line of Spongebob Squarepants instruments this month after completing a new deal with Nickelodeon.
The firm - which already has a Spongebob Uke and junior acoustic guitar in the market - will roll out a junior electric guitar, a full size electric guitar and two new ukes, all decorated with images of the character.
One ukulele and one of the guitars will be adorned with images of Spongebob's face showing his many moods. The other ukulele shows the character smiling with his friends under the sea, while the second guitar will show Spongebob in a guitar hero pose alongside the words 'Make it Loud' and 'Screaming Spongebob'.
Dennis Drumm, MD of JHS, said: "Spongebob is a funny, quirky and very cool character - with a strong appeal to a market that loves music and musical instruments. We are thrilled to have the opportunity to work with such an iconic brand.
"Creating these instruments has been the most fun thing we've done in 45 years and our customers just can't get enough."
Nickelodeon's UK licensing manager, Ashley Holman, added: "JHS has combined the quality for which it is rightly known with some wonderful designs that perfectly capture the appeal of Spongebob. We're sure that Spongebob's legion of fans will be delighted with these marvellous instruments."
