Andy is a green frog with green spots and no ears/nose. He wears a blue beret and orange shorts. His feet are long and have three toes.
Andy is an artist who is quite skilled at painting, sketching and other forms of art. He is also good at photography.
His mother is a costume designer for the traveling circus and his father is the prop designer, which acts as his inspiration for wanting to become an painter.
Of the trio, Andy is often portrayed as the most interested in his unfamiliar surroundings.
However, he becomes more comfortable after he learns more about each nation's culture.
Though he does get grumpy every now and then (like in "Stairway to Art Day", "Rhinoceros or Bust", and "The Potato King") and got into a fight with Carmen once, he is the nicest kid of the trio (Carmen previously held this title, but has become more demanding, self-centered, and dismissive), as he wants to make friends with everyone and is rather friendly and outgoing.
Andy, his family, and friends are part of a traveling circus known as "Circo Fabuloso", which travels around the world. As a result, He, alongside his friends Carmen Mariposa and Leo Chockers are never living in one area at once, and become unfamiliar with their surroundings. Luckily, the three of them have Luna the Moon who travels with them all the time, and knows almost everything therein to know about the country they are located within at any given point.
Many of the episodes pertaining to him often focus on him understanding the concepts of different nation's artistic cultures to help him solve personal problems, such as the meanings of murals painted in Mexico City, or how to effectively read hieroglyphs in Egypt. With the knowledge, Andy becomes confident over how to impress his family and friends with his new findings.
In "Pulling Strings" he and Carmen denounce their friendship after the two argue what they should do that day. The two of them later reconcile after watching a traditional Indian Kathputli play, which combines art and music together.
