Go to Wimpy wonderland island. You’ll see Greg, talk to him, and apparently, his little bro, Manny. Go to Greg’s house and search for clues. Go left, to Surrey Street. Go upstairs, and go here.
Get the address book. I already get it! Go to the other room, that’s Greg’s room. Get the page of Greg’s Journal(more like diary!). Here’s the page:
Go to Manny’s room, go right, and seems like the window’s open! Exit the house through the window, and you’ll see Manny’s footprints.
Follow the footprints until you see Rowley.
Talk to him, and someone stole his rumble bike! He blame the Whirley street kids, but Manny stole it.
