None. Several characters are seen wearing swimsuits. That's all.

Yu disguised as a ninja attempts to catch a rare spider, but accidentally catches Ai with his net. He let's go of her and finally catches the spider.

Risetto-san (Mr. Reset) tends to scream and yell at some other characters whenever he gets mad over something. This is all played for some laughter.

A cave crumbles. All the characters who are inside the cave barely manage to get out of there before they could get stuck inside it.

Several scenes have characters fall into some pit holes. These scenes are mostly made as comic relief.

Yu calls Buke (Bouquet) something like "swabby", while he and some other characters are inside a cave on boat. This depends on the translation.

During a scene involving a huge dinosaur fossil, Yu utters something which could mean "damn", twice. Again, this depends on the translation.

Yu calls several other characters "sea dogs" while escaping a crumbling cave.

This is all based on the translated version I've watched. In other words, no profanity which could be harmful to any children.

None.

Risetto-san (Mr. Reset) tends to pop-up right in-your-face by sudden whenever he gets mad at other characters. It is however all played as comic relief.

Main character Ai arrives at a dark room filled with scary-looking skeletons. Ai is seen to be scared, until it is revealed she had arrived at a dinosaur museum.

Ai gets to learn about Sally's sudden departure. This scene may be kinda emotional for some very young children.

This Japanese animated movie is pretty much a G-rated film.
