Tunnel King - S1.E26

The Creeper is accused of stealing from the Animalians, but without any hard evidence, Livingstone refuses to blame it. Encouraged by Tyrannicus, the enraged Animalians rush into the tunnels. It's a trap, however, and they become stuck. Meanwhile, the Creeper tries to sabotage the Core but is thwarted by Allegra, the only Animalian not in the tunnels.
