In "The Dinner Dance", Snow White gives a dwarf a kiss on the head. Dopey tries to get one kiss too, and ends up getting one later.

In "Ariel's Treasures", mermaid's are wearing small bras, while mermen are shirtless. This is very typical for Disney's "The Little Mermaid" franchise.

None in "The Dinner Dance", unless you count with an explosion which is heard by six dwarves. Nothing bad happens.

"Ariel's Treasures": Ursula the Sea Witch makes human things go berserk, and eventually attack various characters. A "twirly-whirly" object makes multiple underwater buildings crumble, but nobody gets hurt.

Some very mild language.

None.

Ursula, who appears in "Ariel's Treasures", tends to look kinda frightening due to her appearance and determination. But this is practically nothing compared to her original appearance in "The Little Mermaid" from 1989.

This film can safely be viewed for everyone.
