New Super Mario Bros. Wii
Yoshi has very oftenly seen in some levels of eatable things and enemies but in fact, he rarely doesn't show up in every level. Sometimes he may eat some things that he could swallow, such as sections from a pokey, or spinies thrown from a lakitu. Yoshi only appears in worlds 1-3, 2-5, 4-5, 6-4, 7-6 and somehow hidden in 3-2, and 5-4.

Super Mario Galaxy 2
Yoshi appears in Super Mario Galaxy 2 as first in an egg and wants out of it. Bowser always orders a Magikoopa to get rid of Yoshi when Mario tries to approach him in some tricky levels. He only rarely appears in the Yoshi Star Galaxy (1-2), and Bowser's Galaxy Generator (6-Castle). Bowser can do many things from Yoshi and Mario, so he doesn't want the plumber to team up with his dinosaur friend.

Yoshi oddly appears in Yoshi's Story, for Baby Bowser turning the Yoshis' Island into a book and stealing the Super Happy Tree for somewhat gameplay. In this game, Yoshi is the main protagonist for saving the Super Happy Tree from Baby Bowser.
