I DIDN'T SEE THE RED PANDA COMING ๐ญ๐โค
I love how you're going with this; it kinda makes sense! Harlequin is 100% a serpent; bro's got the tongue and most symbolisms (even sxual desire ๐).
But Colombina actually means 'little dove', FYI, which represents innocence, new beginnings (hum hum, sacrifice) monogamy/love (explains why she didn't want to be with Harlequin since she is already with Pierrot).
