We heard your question and have gone to test it out. No longer do you need to live in fear of being swallowed whole by a blue whale.
Normally, a blue whale will directly spit you out due to literally being too big to swallow. Blue whale threats are in fact only around 4 to 8 inches in diameter and don't have the size required to swallow you whole.
There is however a very slight chance that the whale will choke on a limb of yours, or in very very rare cases, your head. If that happens... may the odds be ever in your favor.
