Tip: When determining a time limit, remember that players won't be as familiar with the level as you are. If you normally complete the level with the timer around 100, others might run out of time on their first try.
This patch fixes many glitches that the Baby Yoshi and the Yoshi Egg sprite have due to lacking checks or routines.
It adds to the Baby Yoshi a routine that makes the sprite disappear when an adult Yoshi is already present in the area and a pointer to an off screen routine that can be used by unchecking 'Process when off screen' with Tweaker should the user wants it.
It adds to the Yoshi Egg a sprites locked flag so it doesn't run routines when the flag is set, a pointer to an off screen routine so it doesn't cause any slowdown, a proper ground detection so it doesn't float in the air and a new proximity routine that checks the horizontal and vertical position of the player when getting near.
It's working quite nice, there's a small note with this patch: if you have more than 3 baby Yoshies their graphics start to show wrong tiles when one is offscreen. The patch didn't add this, though, it happens on a vanilla ROM as well.
