On the title screen, Type in "TOTAL WORMAGE" for SHEEP MODE. If you are using a joypad press GREEN, UP, PAUSE, PAUSE, YELLOW (which spells GUPPY - a tribute to the late Bananafish). This gives you 3 sheep, 1 banana bomb and a minigun straight away (go into Weapon Options if you need an UNLIMITED SUPPLY of sheep)
The "legendary prod move" is a not available in any shops. To activate get next to your victim and press AWAY, AWAY, TOWARDS, TOWARDS (in other words, if your worm is facing right press left, left, right, right)
Stand next to a worm (not your own) and then press away, away, towards, towards then do a prod and you get a secret move.
Select your four players, then select two of them again (They get circles instead of stars) you are now ready to play team worms.
The custom level option is EVEN MORE EXCITING than you thought. You can set the gravity, friction, sky and water colours for your levels. Instead of saving your level as FISHCAKE.WRM, save it as FISHCAKE.????.WRM (the 4 question marks being 4 numbers).
You can also make your own message appear, when your level is chosen, by giving your level file a comment. You can do this from Workbench by clicking on your level files icon and choosing "Information" from the Workbench menus. Then just type your message into the "comment" field and click save.
