Thought of some more "long-cario" ideas that loosely reference more of the five senses (since you have Smell and Taste in the form of Lie and Lick respectively) that you're welcome to take:
Sight: Lucario with naturally good eyesight. But they also have an extendable neck that's flexible like a snake or something, which helps 'em see stuff even better I guess. also a bit less unsettling than the idea of "long eyes"
Hearing: Lucario with BIG, l o n g ears. Almost like a GMax Cinderace. Maybe they also function like arms and have ear-hands or something. Or maybe they're just ears, idk.
can't think of a "touch" based idea :(
Characters with comically oversized lop ears make me think of Klonoa so I dressed him up like Klonoa. The actual design probably needs some work, but this is a decent first draft.
The boy on the left is probably the quiet sort, not quite as nervous or shy as Lie-cario but still more likely to let others handle most of the conversation. The one on the right is very friendly and happy to meet you, and loves getting to know new friends.
I'd say the left one would probably have to be Ear-cario, since "listen-cario" doesn't flow as nicely. For the right, Look-cario would probably have to do, but I'm still uncertain. Leave name suggestions in the replies!
