Yoshi Skip

About the skip
In the fifth episode of Pianta Village, there is a pipe covered with goop that only Yoshi can clean. Yoshi skip allows Mario to bypass the goop and enter the secret without Yoshi. This saves time in that you do not have to get a fruit for Yoshi, and in routing since you do not have to enter Pinna Park to unlock Yoshi before Pianta Village.
