Meet the Characters
Theo the Tadpole
Theo has always been a tadpole, swimming happily with his tail. When his body starts changing, he does not know what is happening to him.
Gus the Frog
Gus is an older frog who remembers exactly what it felt like to be a confused, changing tadpole many seasons ago.
The Story

Theo had always been a tadpole, a small, wiggly shape swimming happily through the lily pads.
One morning, he noticed two tiny bumps near his tail that had never been there before.
“What is happening to me?” Theo wondered, twisting around to look at himself.
Over the next few days, the bumps grew longer, turning into two wobbly little legs.
Theo panicked, swimming in fast, worried circles. “Something is wrong with my body!”
An older frog named Gus swam over, watching Theo’s worried circles with a calm, knowing look.
“Nothing is wrong,” Gus said gently. “You are simply becoming a frog.”
“A frog?” Theo gasped. “But I’m a tadpole. I’ve always been a tadpole.”
“You were always going to become this,” Gus smiled. “It just takes time, and it can feel strange while it happens.”
Theo wasn’t fully convinced, but he stayed close to Gus as the changes kept coming.
His back legs grew strong. Then two smaller front legs appeared. His tail, once long and useful, began to shrink, just a little, every single day.
“My tail is disappearing,” Theo said one evening, more curious now than scared.
“It will,” Gus nodded. “You won’t need it where you’re headed.”
Weeks passed, and slowly, Theo’s tail vanished completely, replaced by four strong, springy legs.
One bright afternoon, Theo felt a strange new urge and, without quite meaning to, hopped clean out of the water onto a lily pad.
“I’m hopping!” Theo croaked, surprised by his own new voice.
Gus hopped up beside him, beaming. “You’re breathing air now too. Welcome, little frog.”
Theo looked down at the pond, at the lily pads, at his own strong new legs, and let out his very first proud, croaky ribbit.
Moral of the Story
This tadpole bedtime story is not about something going wrong. It is about what Theo discovered as he trusted a strange, slow change happening to his own body. For kids going through their own big changes, his new legs show that feeling unsure is simply part of becoming something wonderful.
Reading Tips for Parents
