I need a few oddball sounds for an animation I'm working on, but despite listening to a few thousand sound effects the past few days, I've been unable to find ones that fit.

Here's a couple examples of I'm looking for:
* A low-pitched rising "boo-wip!" noise like one might hear when an informational bubble window pops up on the screen.
* The sound of someone biting into a very juicy, slightly crisp fruit, like an overripe cantelope.
