A Surprise For Frog

Rat returns from a long journey. He brought a present for Frog.
It looks just like an onion…
"Can I eat it?" asks Frog.
"No," says Rat, "it's a bulb. If you plant it now, you'll get a surprise in the spring."
Frog thinks he's waiting a long time. But then finally, a small green dot appears above the ground...
The tip grows bigger and leaves appear.
On a beautiful spring day, Frog's friends come to see the surprise.
Rat claps his hands. "It's a beautiful tulip!"
Frog sighs contentedly. "Beautiful, isn't it! I took good care of him."
Experience autumn, winter and spring with Frog and discover what the surprise is.
The Frog Tulip will be on display in Keukenhof.
