Grammar correction for a 5-year-old: Anteaters don't have teeth — they catch ants with their long, sticky tongues

Corrected sentences:

Anteaters don't have teeth. They catch ants with their long, sticky tongues.

Why this is correct (for a 5-year-old):

1. We use don't because it means do not — that is correct when we talk about more than one anteater.
2. We say tongues (not tongue) because they means more than one anteater, so the body part word must be plural.
3. We use long, sticky because an anteater's tongue is very long and sticky. That helps it pick up lots of ants quickly, like a sticky lollipop picking up sprinkles.

So the two short sentences tell the idea clearly: anteaters have no teeth, and they use long, sticky tongues to eat ants.
