Mario, Luigi, and Yoshiarta go camping. Luigi starts the video yelling, "GO WEEGEE GO WEEGEE GO WEEGEE!" BigYoshiFan's iPhone said it would take 1 hour and 23 minutes to get to the campsite.
They did some things like bat and ball and Cooking with Yoshiarta.
At the campsite, Mr. Bollox wanted to go to the bathroom, so he went to find the toilets. Luigi followed him to lock Mr. Bollox in the bathroom stall. Mr. Bollox actually enjoyed being in there, as it was mentioned later.
And for more info see Bat n' Ball Tournament.
