THEY have their own show, their own movies and now The Muppets have their own periodic table.

The puppet creations of the late Jim Henson are so popular and varied you'd be hard pressed to remember all of them.

But thanks to designer, Mike BaBoon, you no longer have to. The designer has created a periodic table listing every single Muppet character ever to feature in Sesame Street or The Muppets.

"Each square represents a different character and indicates the primary Muppeteer(s) for that character, as well as the year and production in which the character made its debut," BaBoon wrote on his blog.

"Borders align with hair/hat colour, background aligns with skin/fur colour, and colour of the abbreviated name represents nose colour (for characters with noses that is)."

Impressive.

So what is the scientific abbreviation for Kermit? That would be "Kr". Fozzy Bear is "Fo", Miss Piggy is "Pg". Bert and Ernie are "Bt" and "Er" respectively.

The table is available as a print, pillow, t-shirt, hoodie, iPad case, canvas and tote bag from online store, Society6 and RedBubble.
