Below is a sample reply to Hopper:

Dear Hopper,

Thank you so much for your lovely message! It was so exciting to hear from you. I can imagine how fun it must be to sit on a big lily leaf pad and splash in the rain!

My name is _______ (write your name). I am a student of Class 5. My favourite hobby is reading storybooks and playing with my friends. I also love drawing pictures of animals — and frogs are one of my favourites!

I think your life sounds wonderful. I wish I could hop as high as you and swim in cool ponds. Maybe one day I will visit your pond and we can be friends in person!

Take care and keep croaking!

Your friend,
_______ (your name)

Below are facts about two chosen animals:

1. Seahorse

• A seahorse is a small fish that lives in the sea.
• It swims upright, using a tiny fin on its back.
• The male seahorse, not the female, carries the eggs in a pouch until they hatch.
• Seahorses use their curly tails to hold on to sea plants so they are not swept away by water currents.
• They eat tiny shrimp and small fish.

2. Octopus

• An octopus has eight arms (tentacles) covered with suckers.
• It lives in the ocean and can change its colour to hide from enemies — this is called camouflage.
• When it is in danger, it squirts a dark ink into the water to confuse its enemy and escape.
• An octopus has three hearts and blue blood.
• It is a very intelligent animal and can solve simple puzzles.

Note: Students may choose any two animals from the list and write similar facts based on their research.
