Baby Yoshi Double Eat
Getting two eats with a baby Yoshi around half a second apart will count as three eats instead of two. Three quick eats will in turn count as five. This is considered glitch tech.

Baby Yoshi can be held, on the ground or in the air for this to work. But if the eats are too quick they will not count. As baby Yoshi starts to eat one enemy but it hasn't completely disappeared (mouth closed, but still enlarged), quickly have him eat a second one to count.
