SECRET AGENT PROFILE
Agent Tyler
- CODE NAME
- Agent Tyler (“AT”)
- SPECIALITY
- Marine biology
- LOCATION

Nothing to Sea Here.
Following several soggy mission reports, Agent Tyler was issued with a waterproof notebook. His underwater pen is useful for taking notes. It is considerably less useful for drawing a moustache on someone who is trying to stop a mission.
YOUR ASSIGNMENT. Design something that helps an agent take notes underwater. What would it need to do?

Your privacy.
For agents.
You can train here without giving us your name, email address or a photo. Your answers and game score stay on this page. We don’t receive them, and they disappear when you reload.
Your browser remembers that you unlocked the spy puzzle while this tab is open. This lets you move between pages without entering SECRET again. It is a temporary setting, not an agent account.
Cloudflare delivers the site. It receives connection information, such as your Internet address, to show the pages and help keep them safe. We don’t have advertising, sign-up forms, uploads or chat on this version.
Keep your drawings with you. Please don’t send your home address, school, passwords or other private information. Ask a trusted grown-up if you have a question about privacy.

Using the training.
For agents.
The Children’s Spy Agency is a fictional spy world. These activities are for fun, curiosity and practising your thinking skills. Completing a mission does not create an account, membership or real spy appointment.
Train somewhere safe. Ask a trusted grown-up before trying anything you are unsure about. The gadget mission is a drawing activity. Please don’t build dangerous equipment, investigate strangers or trespass.
Keep drawings and mission reports with you. This version has no upload service or public gallery. Remember Protocol 14. Don’t hurt people, or anything else that might have feelings.
