00:00 - The rex growls and roars, posturing before its would-be opponent, Zusanna
00:09 - The two titans run at one another before clashing and wrestling
00:25 - She manages to get the upper hand, pinning the rex. It tries to thrash and bite "Stay down! So I can swallow you!"
00:38 - She lifts up the rex's muzzle to her own mouth with drawn out ahhh.
00:40 - Taking her time she stuff the rex's maw in her own and starts to swallow. The rex can be heard struggling, feet scrambling against the dirt. Until it gets lifted off the round and finally the tail gets slurped down
01:15 - Zusanna gives a satisfied burp and a laugh and pats her belly, which can be heard bouncing and sloshing
