GuerillaBox is a service that centralizes communication channels with customers for businesses and individuals. The design for this Sign Up form uses the brand’s icon, a gorilla, who guides the user through the process of creating an account. 

To avoid overcrowding the screen with gorillas, whenever an error message pops up on the Sign Up screen, the introductory, excited and inviting gorilla disappears, and a here-to-help one appears near the error message. Ideally, of course, they will both look the same, designed to match the brand’s mascot.
