"The specials friends of Acorn Green."
Acorn Green were produced by Tomy in 1986-87. The characters, all woodland animals, first appeared in a UK comic book, then came figures, plush toys and other accessories.
There were 36 comics and two annuals produced, sold in the UK.
According to Wikipedia, "a preview comic was seen in Get-along Gang comic the week before the first comic was released. When the comic ceased in July 1987, it lived on as a single story feature in the Muppet Babies comic, also by Marvel UK."
