Aviva is the worst offender. Her butt is usually shown in a sexual pose/manner. She and Chris are constantly flirty/romantic with each other.

This is a show just like Total Drama or The Simpsons. Sometimes it's OK for kids, but mostly for older tweens/teens+.

In one episode, the brothers lose their clothes during a fall and have to cover themselves with palm leaves in order to remain decent when they're sneaking back into the Tortuga.

Some very mild violence between animals on occasion.

Some episodes have animal gore, but it is rarely detailed

Blood is very rarely shown when an animal is killed by another animal on-screen.

Zach calls the Kratts, Wild Rats; this is an insult, but nothing too bad.

most of the time when people say "wild kratt" it sounds like "wild cr*p"

Nothing too dark, however the villains often steal animals. This may be upsetting to some very young viewers.

The main characters all frequently get into life-threatening situations, typically caused by a villain. Gourmand is their deadliest foe. For example, he planned on cooking Chris and left the brothers to get killed by African honeybees.
