Certainly save the other clips you mentioned... Either keep them to edit another series of clips together like this, or they can help piece-meal together a script...
You might be surprised how much ordinary "filler" gets used in animation to break from one scene to the next in a narrative... AND I know... You're still developing the character, probably don't have a narrative in mind just yet...
BUT don't underestimate how easily a developing character can spawn or inspire a story... They grow and the story grows... It's a symbiotic relationship, and you can get there...
Only thing to note is be careful about the rush... a couple clips almost cut-scene to the next too early to feel quite finished... Happens a LOT in (professional) skit and compiled series... SO not to worry...
You've obviously got the skill and passion to put this out. It's good work... Looking forward to see you grow. ;o)
