2.You'll also see a picture if Tingle's Face in Ferus's house, which is in Wellspring Station in the Snow Realm. It is on the right side of the room inside his house. (It's a little blurry)
3.You'll find a Tingle Statue in the Trading Post, where Lineback III is. It is on the left side of the Trading House Room where you meet him.
