Finceline (Finn X Marceline)

We all know that PB is 18, right? Well, she's just like Marceline. She looks young but is actually older than she looks. Proof?

1) In Princess Cookie, she visited the kẹo Orphanage. Baby Snaps was still a kid there, and Bubblegum looked 18. It was the past. While Cookie has grown physically, PB still remains the same.

2) In the promo art for Burning Low, Flame Princess seems to very young, like 5 years old. While Peebles in tiếp theo to the lantern, looking 18 years old.

3) In The Suitor, the oldest suitor đã đưa ý kiến he had been waiting for PB for 300 years. Indicating that she has lived for 300+ years. I think that it is because of kẹo Biomass that makes her live.
