How to unlock the Shenzi, Banzai & Ed achievement in Kingdom Rush Origins - Definitive Guide
Hyenas become scared if one of your infantry units (Hero, barracks, reinforcements, etc) tries to engage in melee combat. To avoid scaring the hyenas, you'll need to kill them before they cross the path of your units. You can presumably also let them reach the goal, as long as there's nothing in their path.
Hyenas will spawn on the northern path starting from wave 3. A couple archer towers at level 2 can keep this wave at bay. Build a third one when you can and upgrade them to level 3. They should be able to kill most hyenas (and plenty of other enemies) on their own. You can use the plants, abilities, or towers further along to get any stragglers if needed. Be careful calling waves early, as they may slip by while your towers are targeting earlier units.
As for the normal level completion, I had two barracks near the goal to stop other enemies, a stone druid near those to hit stopped enemies, and a barracks and mage by the bottom waterfall to slow shortcutting enemies.

On level three, "Waterfalls Trail", you need to avoid "scaring" no more than three hyenas. You scare them by having melee units near them, which causes them to run faster through the map. Avoid using the Barracks, reinforcements and your hero in the area marked in red, as that is their pathway. The lower path is fine, as no hyenas spawn from that section of the map:
