***Notice***
There is a hidden exit/alternate route in 1-3 that leads to a Cannon; to see how to get there, search for my "Missed Hidden Exits Compilation" video.

We continue with my Let's Play of New Super Mario Bros. Wii with Level 3, and a few Mushroom Houses and mini-games are shown as well.
Eventually, Bowser Jr. leaves Mario a note, saying he's sent some minions to kidnap a Toad; you'll see the kidnapping on the map screen. The enemy will go to a previously visited level, and will hide the Toad in a ? Block. Once you find him, you'll have to carry him to the end of the level.
I'd imagine in some levels, it's easier said than done.
