She is known for her problem-solving skills. She makes her way through the forest slowly and thoughtfully. Always a step ahead of the game, she is ready to provide essential information that Dora and Boots need to complete their journeys.
Isa is a gardener and nature lover. She loves to help her friends Dora and Boots, and they are always ready to help out with her flowers. Her garden is full of surprises, from talking exotic plants to her very own rocket ship. Once, when Isa wished for her sunflower to grow really big, she needed Dora's help to get back down.
Isa is quiet and can easily blend into the background, especially in forests and gardens like her own. Her color gives her a natural camouflaging ability. She is very good at playing hide and seek.
Isa loves all of her friends but especially likes to spend time with Boots, whom she has a crush on and knew long before she ever met Dora. Isa treats both Dora and Boots equally, but she always greets Boots more shyly than Dora. An early promotional image features Isa looking at Boots with hearts.
Isa is mostly green with many light green spikes along her back and tail. She has round white eyes on the top of her head, each with four long eyelashes. Like Tico, she has small triangular stumps for arms and legs. In the first season, early season 2, and the season 3 episode Journey to the Purple Planet, she is forest green, and in all later seasons, she is lime green.
In the spin-off series Dora and Friends: Into the City!, Isa appears in two episodes: "Return to the Rainforest" and "Dora's Rainforest Reunion." She also makes a cameo appearance during the animated segment of the theatrical movie Dora and the Lost City of Gold.
- Isa has her own leitmotif that plays whenever she appears or is mentioned (C-G-A#-C-G-A#-C).
- In the French dub, Isa is said to be a monitor lizard rather than an iguana. Her name is changed to "Véra le varan" (varan is French for a monitor lizard and not iguana).
- Not surprisingly, Isa has a bit of a crush on Boots as she often says "Hi, Boots" in a slightly higher pitch voice.
- Isa appeared on the Dora and Friends: Into the City! episode "Return to the Rainforest".
- In the episode, she introduces Dora to a young flower who lives in her garden named Bud who had grown up hearing stories about Dora and her adventures from Isa and was excited to finally meet Dora. At the end of the episode, Bud ends up getting sewn into Backpack by Kate while she was repairing her, however, Bud is fine with it as he gets to go on adventures with Dora.
- Aside from the Pirate Adventure photo in Journey to Jaguar Mountain, Isa never makes an appearance in Go, Diego, Go!.
- In Season 1, early Season 2, and the season 3 episode Journey to the Purple Planet, Isa is dark green, but in later episodes, she's light green.
- She is able to blend into her surroundings, although she often wears dresses.
- Isa got a character find only twice: Choo-Choo! and El Coquí.
- She is always a helpful friend to Dora and Boots.
- She grows a wide variety of flowers in her garden.
- She is the same age as Benny, 6 years old.
- Her third voice actor Skai Jackson also did the role of the Little Fish from another Nickelodeon show, Bubble Guppies.
