The unusual, animated characters with large eyes and tentacles.

The ad opens with a close-up of a pink, alien-like character with large eyes and tentacles, wearing glasses and sitting at a computer. Another similar character is visible behind it. The scene is dimly lit with purple and orange hues. The camera then focuses on a hand-like appendage manipulating a lever. The characters reappear, looking at the screen. The final scene shows a product box for Allegra and text overlay.
