Dekkin and Artie  from Spaceman Jax Universe - Curio & Co.

Spaceman Jax's 7-year-old niece is an energetic little firecracker. Despite her adorable sweetness, she loves nothing more than to jump into the action and take on the Mantagons, much to the dismay of their home service robot RT, who tries to get her to do her homework and go to bed on time.
