A collection of t-shirts is set to join the existing plush, posters, greetings cards, calendars and homewares lines for Monkey.
Bulldog Licensing has appointed BCI to produce the range.
The firm joins Posh Paws, GB eye, Danilo and Bluebird Brands on the licensee roster. Monkey's licensor is Comic Relief, with all licensed products sold helping the charity.
"Monkey lends himself perfectly to apparel, so we are delighted to have signed this new deal," commented Rob Corney, Bulldog MD. "The brand benefits from huge awareness and everybody loves Monkey, whilst having Comic Relief as a licensor makes him even more attractive to licensees.
"All this has enabled us to develop a programme that just keeps on growing."
