Guess you love fishing! BTW, the OP lives in Malaysia!
If you look at this chart: Nutritional Values of Amphibian Foods; will see that although superworms are not listed, similar beetle worms are very high in fat. For that reason, they are not recommended as a staple food and are nutritionally inferior to earthworms. I have no experience with Pacman food (imagine Samurai?) so won't comment on it.
Night crawlers are a large species of earthworms. In U.S. most are Canadian NC; but you can also get European and African NCs.
