A turtle is flushed down the toilet, but makes it out alive. It is later kept at a lab for research. At the end when the turtle has grown in size, it is being shot at by the army/tanks.
Totally safe! I almost turned it off at the start because the main character is acting super anxious and in the first 5 minutes he is having stomach pains which are comedically exaggerated, but nothing ever happens or even comes close. Overall it’s a very sweet and PG movie and doesn’t have any of the explicit violence or shocking material of Sion Sono’s other films.
