What actors and actresses appeared in Peep the Big Wide World - 1988?

There seems to be a misunderstanding. "Peep the Big Wide World" is not a film or television show with actors and actresses. It is a children's television program featuring puppets, created by the BBC in the 1980s. The characters were puppets and were operated by puppeteers.

The program was primarily educational, aimed at preschoolers, and focused on nature and the world around us.

If you're interested in learning more about the program or its cast of puppets, I recommend looking at online sources dedicated to British children's television.
