Character concept Imma use

She is a cinnamon roll goblin dressed in very bright colors. She's a pastiche of dora the explorer, talking to an unseen audience, asking where obvious things are, and to cast spells, she goes "can you say {spell name}?"

The audience she talks to is a baby eldritch monster that she has to teach about the material plane, and gets powers as payment from the monster's parents

She's a hexblade warlock, and her weapon is an impractical two-handed weapon that looks like a crayon drawing, drawn by the baby monster. It's details are different every time, and to summon it, she asks the monster for something to help her fight

I rather like the idea and reminds me of a card from Magic the Gathering called "Toby, Beastie Befriender", pick of the art work below:
