There is a robot with a dollar sign on its head

Create a mascot for the startup Pague Bem Brasil, a fintech focused on automated billing solutions and efficient communication with clients through channels like WhatsApp. The mascot should represent the company's values: innovation, efficiency, accessibility, and a friendly yet professional approach. The design should be inspired by the colors and style of the company’s official logo, which uses green, yellow, and white, and it must incorporate the dollar sign, which is the brand's symbol. The mascot should have a modern and friendly appearance, capable of creating an emotional connection with users. It should incorporate elements that represent effective communication, like message icons, as well as symbolize efficiency and agility, such as gears or a lightning bolt. The dollar sign, as the brand's symbol, can be creatively integrated into the mascot's design, perhaps as a detail on its body or as an accessory. The character should be adaptable to different situations, from friendly interactions to more formal moments, reflecting the communication stages of Pague Bem Brasil. The primary colors should be green, yellow, and white, in harmony with the company’s logo.
