Lists of Mascots

Lists That Have Been Completely Integrated into the Above List

Sources, completely covered:225)

Lists That Have NOT Been Completely Integrated into the Above List

for this is the name by which a picture of the wizard is summoned in the imagemagick program
also known as 🐸TTS in project documentation
KDE Advanced Text Editor
Amphiprion Percula
listed as Celtic Sun God in some places
Officially there is no official name

one anonymous source in personal communication imaginatively gives as aliases for this apparently unnamed mascot “Yhtraccm” (“McCarthy” backwards), Namssuseleets (“Steele” and “Sussman” backwards), “λambdy” or “lambdy” (diminutive form of “lambda”), and “yambdaλ” or “yambdal” (presumably a form of the word “lambda” with some semblance of rotational symmetry)
“lispy” would also seem fitting to me.
it is unclear if some or all of these lists may have expanded since they were last investigated
