If your're desparate in finding this plant, then try bugbitingplants.com, they are seemingly the only nurserie that sells this plant.Just keep in mind that its quality will be poor but if you have the right conditions, you might be able to nurse them back to health.
Buy from them at your own risk!!!

I've never heard of the name, but if you can post a picture or provide a scientific name, I can point you in the right direction.

What are jungle bells?

Jungle Bells is a Nepenthes Hybrid put out by EP (Exotica Plants). They used to be fairly common about a year ago, but now the stock is running out as people have bought them up. I believe the suspected parentage of the plant is Ventricosa x Sibuyanensis. While bugbitingplants.com used to carry them, I believe they are now out. Some of the other CP Vendors occasionally have them, and or rooted cuttings.

What's it's scientific name?

As I said, the suspected parentage of the plant is Ventricosa x Sibuyanensis... so that would make it 'Nepenthes Ventricosa x Sibuyanensis. A hybrid.
