Characters

Filu is a warm-hearted, lovable 7-year-old Cocker Spaniel. In his grandfather's house, a clever Professor, he discovers Wonder and gets to keep her safe, because Grandpa trusts him completely. Together, they explore the world and go on exciting adventures!

Paula is Filu's brave and fearless best friend. Where Filu hesitates, she jumps right in. She's one of the few who knows Wonder's secret and shares a deep friendship with them both!

Wonder is a curious, warm-hearted star from a faraway planet. She wants to learn all about the world and can grow, shrink, and even talk to animals. Together with Filu, she explores the world but no one must ever see her, or her planet could be in danger!

Grandpa Woof-Woof is a Professor. A brilliant, wonderfully chaotic inventor bursting with new ideas. Because he trusts Filu so much, he lets him take care of Wonder, so the two of them can explore the world together.

Master Shiba Inu is a wise mentor and master of martial arts. He always has good advice for Filu and his friends!

Mr. Pig is Filu's sweet, cheerful pet piglet who never leaves his side and always senses when something's about to happen. His one danger: the Countess, who has taken quite a liking to him.

The Countess has everything money can buy, and still wants more. She's rich, greedy, and always scheming up something. She senses that something secret is going on with Filu, and she's determined to find out what.

Hector is the Countess's clever, slightly sneaky cat, always by her side. He still has an old score to settle with Mr. Pig.

Mali is Filu's 11-year-old sister. A creative whirlwind and aspiring fashion designer, just like her brother a Cocker Spaniel through and through.

Nothing gets Mami stressed out. She loves Papi's crazy inventions and enjoys inventing new things herself.

Filu's dad is clumsy and hilariously funny, but always ready to help, with a big heart and a laid-back vibe.
