A series of ceramic Muppet planters featuring Animal, Kermit and Beaker are available in the UK.
Beaker's design works surprisingly well.
Much like a chia pet, the plant's foliage creates the hair. A plant with tall straight stems and branches would work best, but seeing Beaker with a curly afro is fun too.
The hair raising fun is endless. Just imagine Beaker with drooping hair or "San Francisco Beaker" with a flower in there!
Available from Amazon UK.
