29 - Alien

I heard about Mario & Luigi: Partners in Time, an RPG where a bunch of aliens attacked the Mushroom world in the past, when the Mario brothers were babies.  I haven't played it yet (I don't have a copy of it and I don't have a Wii U yet).  And among those aliens, there was a Yoshi-like creepy monster that attacked Yoshi's Island where it tried to turn all Yoshis into monsters.
I decided to incorporate it into the "Yoshi & Ishimaru's Halloween Arc".  After facing flying knives, a power outage, then a bunch of native monsters popping from the dark, Yoshi and Ishimaru thought the episode was over, but as soon as they come out from the building, they quickly find out the village is attacked by a Yoob.  They find a hiding spot, under a deck with a barrel next to the stairs and they're both really scared.  Yoshi is worried about both of them being found by the alien monster, and Ishimaru is worried about not be able to SMS for help for she couldn't find her phone.
