Yoylese

Yoyle Hieroglyphs are hieroglyphs used as the language of Yoyleland, (and non-canonically, all of Northern Goiky). The first to read it in any video were Golf Ball and Tennis Ball.

Mentions
They were first mentioned in IDFB, inside the Science Museum. They appear as a sign naming the Yoyle City Science Museum above its English equevilent, as well as being featured as labels of items in the Science Museum.

Appearances
Some of the hieroglyphs look like a triangular infinity sign, a close square bracket, an upside-down flag four, a hyphen, a Z, a spiral, a 3 with a long tail, a triangle, a 4, something that looks like a dash connected to a pipe (|)

When GB and TB come across the Science Museum, Needle says that FreeSmart has a secret involving this museum.

Other References
The hieroglyphs can also be reffered to as "Yoyle Writing" or the "Yoyle Langauge." They are not reffered to outside of IDFB.
