There are 150+ Yoshi's on the map:

• 40+ stands
• 50 food trucks
• 62 drive thru's

Speedrunning all Yoshi's (or all drive thru's / trucks / stands) could be a very fun and creative speedrun category that requires route planning and driving skills. A location counts when the player collects the food item bag.
