MAJOR ENDING SPOILERS BELOW:

Daniel Quilp tends to utter some insulting words to others, like "idiot", "stupid" and "fool". Once he calls a dog a "coward".

Very brief references to wine and beer, since the rest are non-alcoholic drinks like tea and coffee.

Only in one scene, a man can be seen drinking some alcoholic drink.

This cartoon film tends to have some mildly dramatic moments throughout.

The ending is a little bit sad for a family-oriented film.

This film is suitable for all.
