Karknoid beetle

Karknoid beetles are giant insectoid creatures which, if Hot Shot is correct, weigh around 20 tons. They are sensitive to sound which is a useful fact if you have a Virtual Sonic Fence.

[edit]Rescue Bots Academy cartoon
[edit]A karknoid beetle on the plant Herboo was threatening the safety of a settlement of Herboovians, prompting a mission there by the Rescue Bot recruits. Hoist initially realized that he had forgotten the code to activate the Virtual Sonic Fence, forcing his team mates to attempt to slow the massive beetle, mostly unsuccessfully. They eventually got the device to work, and when the beetle broke the barrier, it was sent fleeing from the loud noises that resulted. The recruits did note that the beetle appeared to have picked up the music code used to unlock the fence. Tune Out
