Well, my favorite levels are Pink Plant Woods, Anguish Lagoon and The Swamps of Forgetfulness, mainly because of the jungle theme of them and second, because I just love their music and that overall jungly feel to them, those deep, lush colors, the rich environment and everything basically. For example, in Anguish Lagoon, how after you defeat Bzzit, he becomes your friend (somehow) and how you can ride him is really cool. And as for Swamps of Forgetfulness, the tension from the rising in the beginning and the water rising with that music is just so good and the part where you ride down the plum is really fun. I've always found it fun to go at high speeds in racing games for example, so I found it really fun to do so in Swamps of Forgetfulness too.
