This is one of the few "Worms" that can survive battle while in Defense Position; use it to create a temporary wall before summoning a more powerful "Worm" monster such as "Worm Victory" or "Worm King".
Use "Worm Xex" to put a "Worm" into the Graveyard to boost this card's DEF.
Use "Snake Rain" to increase its defense to 2000 or 2100 if you discard another "Worm" Reptile-Type monster.
Use "Battle Mania" to force your opponent's monsters to attack this card, if their ATKs are lower than this card's DEF. By that way, you can activate this card's second effect many times.
