The Fixies?

A character in red armor runs forward in a dark, cavernous area with stone pillars, while a large, glowing yellow tiger-like creature charges toward the camera from the center of a group of characters engaged in combat, surrounded by colorful magical effects and spells. The scene is set in a dimly lit cave with a blue light source on the left, and the action unfolds as the characters and creatures move and fight, with the tiger creature briefly appearing in the foreground before the focus returns to the central battle.
