The first shot of them at the zoo, you can see Mackie off to the left on someones shoulders
At the German Train Station, you can see him and Jessie follow Tay
You see him several times in Ike's Redwood Documentry
You can see him twice at the monkey forest.
You can hear Mrs Adams say to Mackie"Mac if you jump at them they'll bite you" in the monkey forest
In Hanson's tour of London, Mrs Hanson is carrying him. The rest of the family is farther up
When they shot the cathedrals, Mac and Avie were caught. Avie's in the pink jacket, and Mackie is next to her
You can hear Mackie yell "It feels like...a SNAKE!" when they are holding the snakes.
He's sitting behind Zac at the Sydney Opera House
When Zac says, "Do you want something to drink?" to Mr Hanson, Mac is behind him, and Mrs Hanson calls to him
When they're showing the food, Mackie's talking loudly in the backround
He's to the left of Tay. They show him and Avie quite a bit!
