Lickitung was clearly meant to be seen as an unsettling Japanese monster with its blank stare (at least in the first couple of seasons in the anime) and disproportionally long and grotesque nonlizard-like tongue despite being a lizard-like creature. Everything I described here is faithfully expanded upon by Lickilicky's beta design which was universally praised.
Then the actual Lickilicky comes, throws all that away, and makes him a cute and safe mascot.
