Mnemonic
[ji-] Jimmy Neutron is in the [4] bathroom of the [-e] electricity plant where he has set up an electric 廾 fence that is drilled into the tile floor 戒 to guard against the crazy floating electric 戈 halberds that float around the bathroom, seeking to kill him. They bump against the 廾 fence and fail to go past it. Jimmy is glad his improvisation has helped him 戒 guard against what was seemingly certain death.
