Galloping Green Meadow
From the Super Mario Wiki
The level starts off with a short path leading to a small slope and a yellow Item Balloon after this. Next is a choice between two paths, a bottom path containing a narrow passageway and a Shy Guy and a top path containing a platform with many beads. Afterwards are a few more Shy Guys and a Fly Guy that Poochy can jump on to collect more beads. This leads to a path with a wooden platform containing the first Poochy Pup. Immediately after this are three Fly Guys that Poochy can jump on consecutively to obtain more beads and a gap with another Shy Guy and Fly Guy. After this is a cave section containing multiple breakable boxes containing beads and the second Poochy Pup. Once Poochy exits the cave, there is a path with a few stumps. The third Poochy Pup is found on the third stump. After the stumps are another Shy Guy and three more Fly Guys that Poochy can jump on to collect beads, which is right before the Goal Ring.
