Unlike the generally acclaimed first film, Tony shows deeper physique towards Cholena (a Native-American female rodent), frequently tries to hit on her.

A man and a woman are briefly seen kissing while the mice are going through the "Tunnel of Love".

Fievel and Tony watches Cholena getting changed in one scene. This can be seen as a reference to sexology, but made more irrelevant as the two mice laugh.

On the Mousekewitz's wall shows a painting on a large mouse swimming towards a naked woman (only showing her bare shoulders). This obscene reference of the female figure is shown twice, while in all other shots, it is obscured by having the image cropped off by camera or sometimes having it superimposed by a character.

Most of the indigenous dude rodents are shirtless throughout.

Many scenes contains fighting and harassment. Even references and suggestions of putting other to death are present, as being almost too graphic for a children's movie.

The evil Chief Police uses Scuttlebutt as a punching bag several times in this movie.

The Indian Chief's backstory on the Lenape faced genocide by the Europeans in one sequence might be too disturbing to some.

The evil Cheese Factory Owner orders the evil Chief Police to turn the Indian cave into a burial ground (genocide).

The sequence where a flood of angry mob are aftering Cholena might be unsettling to some as the protagonists, Fievel, Tanya, Cholena, and Tony, are pushed, thrown, trampled, and being separated from each other by the mob.

A racial term "Injun" is used by antagonists several times in the film.

One rat is named "Scuttlebutt".

Squeamish dialogues, like "out for blood" and "split your noggin", are very uncommon for a kid's movie and might be unsettling to some viewers.

In one sequence, a flood of angry mice mob Hellishly raging as they are aftering Cholena, which are heard in forms of racial threats.

Most of the villainous rodents drink wine in a night club. One is briefly seen smoking a pipe.

The Indian Chief sniffed at the soup Fievel gave him and describing it as "strong medicine" in a stereotypical accent, which is most likely referred to a "drug".

References of racism from the villainous rodents are implied.

For a G rated film, it's very questionable for the racially insensitive scenes and suggestive references. Movies with such concepts would have earned a PG or PG-13 rating today.

The scene where Fievel and Tony entering an underground tunnel with skeletal corpses (a result of genocide aftermath) may be too frightening for small children.
