As both Hacker and the CyberSquad go off in search of a giant cyber-slug, the kids realize that Hacker has a listening device that taps into their communications system. The kids decide to devise a secret code so they can send messages back and forth without Hacker understanding what they are saying. The code involves numbers, which are associated with pictures, and it's used to send messages explaining where the CyberSquad should travel to find the cyber-slug.

Here are some Frame, Focus and Follow-up suggestions for using this video in a math lesson.
What is Frame, Focus and Follow-up?
Frame: Have you and your friends ever communicated using a secret code? If so, can you describe how you came up with the code? You can come up with virtually any type of word or number or image or sound to represent something you want to communicate, but you just have to make sure the person on the receiving end knows the code as well. Can you think of reasons why someone would choose to communicate in code?
Focus: Watch to find out how the CyberSquad creates their secret code.
MATT: Now that we've sent Hacker on a wild goose chase...we can make up a new code for sending our messages.
JACKIE: We need a rule that no one knows but us.
DIGIT: And one that doesn't use my cook book, okay?
INEZ: Digit, you're brilliant!
DIGIT: Huh?
INEZ: Let's use pictures for our new code. Each picture will tell us something different -like who we're talking about - what to do, and where to go. Say, cheese.
DIGIT: Wow!
INEZ: This picture could mean 'up'!
DIGIT: I've got all kinds of pictures we can use for words, in my album!
JACKIE: We've got Hacker...the Grim Wreaker...Motherboard...
MATT: Hey Didge, you've even got postcards in here!
MATT: Pizza Canyon...Donut Volcano...there's even one of Icky!
MATT: Who knows, we could win the Academy Award for best picture code!
INEZ: Two copies of the code - one for each sub.
DIGIT: Can we take this one over, I wasn't ready? Hey, there's a number on the back!
JACKIE: I wrote them so we could radio numbers to each other instead of words – that's what makes it a code.
MATT: Say this is the message I want to send to you. Can you read it?
DIGIT: Um...Icky...is at Donut Volcano.
MATT: Right! But to send the message in code-- you turn the pictures over...
MATT: And radio the numbers: 5...12!
DIGIT: So you find the pictures you want – put 'em in order to tell your message – turn 'em over and radio the numbers in the same order...I got it!
DIGIT: Let's find the Ickster!
DELETE: Over there, boss! That looks like one of those cross-ants.
HACKER: For once, Delete, you're right. Let's see if that slug's inside!
BUZZ: Eh, no slug in here, boss. Nuthin' but nuthin'!
HACKER: Don't be so sure. Remember, that overstuffed ball of slime can camouflage himself!
HACKER: Keep looking!
INEZ: No sign of Icky here.
MATT: 5...3...14!
DIGIT: They found him!
INEZ: Didge, look for the numbers on the back of the pictures: 5, 3, 14.
DIGIT: Got 'em!
INEZ: Now arrange them in the same order as the coded message.
DIGIT: 5...3...14! Done!
INEZ: Now turn them over, read the pictures - and tell me what the message is.
DIGIT: Icky...bottom...Pizza Canyon!
INEZ: We're on our way!
