Caring for the Kusaks

This is considered to be the hidden collection of the new Nym's Theme Park.

You need to feed 10 Kusaks located around Nym's Stronghold with weeds. You have to have collected a weed in the Weed Whacker Collection before it is an option to Feed to a Kusak.

Some are stationary by the Quartermaster:
 * Runt
 * Bedhead
 * Blinky
 * Scarecrow
 * Slobbers
 * Troubles

Some are roaming and following a random path at each server reset:
 * Wart Face
 * Gargle
 * Ding
 * Speedbump

What the Kusaks eat is different for each player. If someone feeds them, they will despawn and respawn. However, some players are currently reporting that the roaming Kusaks are nowhere to be found.

Tips:
 * The order in which they are fed seems to be important. For example, I tried to feed Weed V to Bedhead several times, but he wouldn't eat it.  But after I had fed all of the other Kusaks, Bedhead did eat Weed V to complete it.  So if you've tried a Weed type on a Kusak, you will always want to try all of them again, after you've fed one.
 * Another thing, I noticed is that multiple Kusaks may eat the same Weed Type. I had two Kusaks that ate Weed I.

Reward:
 * Revenant Backpack
 * ? XP
