Floating Pygmy Glitch

While feeding the t-rex some tasty BOB I noticed that if you throw the spear at the t-rex so that it hits the t-rex when the pygmy is inside his stomach but still has his name showing up then the pygmy will pop back out but float a bit higher than the normal pygmies for a few seconds:
Also seeing as this is my first proper post I'd just like to say hi to everybody.
