"found out that unlocking Vector requires Pockys. Now I wonder why~"
Well, you see, as a typical crocodile, Vector gets a little peckish. An effective way of luring him out would be to provide him with a sizable meal. He's a big guy. He needs a lot of food... a dozen pocky, a few chao, and throw in a nice workout session with Gemerl to help burn off all those calories. Afterwards, they can both go visit Wario and Waluigi on Yoshi Island to paint some eggs and then go "Say hi to The Eggman" afterwards. Easter's all about togetherness! ...probably. I don't know. The important thing here is that Vector looks great and so does his colorfully-scrumptious dinner.
Happy "late for some while appropriate* timing for some" Easter to you as well, Cami.
