Method number 1: Enter the game with it.
Edit Objects Dialog Box
Use Logic: GruntStartingPoint with Powerup: = 20 ... other fieldz as necessary
Method number 2: Cover it up.
Edit Objects Dialog Box
Use Logic: CoveredPowerUp with Powerup: = 20 ... other fieldz as necessary

Method number 3: Leave it in plain sight.
Edit Objects Dialog Box
Use Logic: InGameIcon with Image_Set: = GAME_INGAMEICONZ_TOOLZ_WARPSTONEZ1 (2, 3, 4)

Method number 4: Put it in a Giant Rock.
No matter what 'team' they are on, a Gauntletz Grunt, (Suicide) Bomber Grunt or Time Bombz Grunt can break or blow up a Giant Rock, or a Shovel Grunt can dig up a Time Bomb next to a Giant Rock, revealing the Tool in the middle, where Tile #290 was placed.

Method number 5: Ask for it.
One of the solver's Gruntz can use a Megaphone to call for the Tool.

This Grunt is carrying a great big Rock that is precious to the King.

He wantz to gather all four piecez together, so everyone may go back home.

Consequently, the Grunt carrying it won't ever put it down, and certainly won't try to hit anyone with it!
You can frequently hear him saying something like "Oh, my back!" while lugging it around
... or complaining "Why do I have to carry the stone?".
While the Grunt carrying the Warpstone can acquire and use a Toy,
he doesn't seem to be able to use a Powerup after he acquirez the Warpstone.

Travel speed: 800 millisecondz per Tile ... 400 millisecondz per Tile with the Super Speed PowerUp.

Tool Use: fergidaboudit!
Tool Use recovery: fergidaboudit!

Used as a weapon

Weapon Use: fergidaboudit!
Weapon Use recovery: fergidaboudit!

'Hit' value: 0/20 ... this Grunt simply cannot fight!

Assumption: Grunt teleportz into an enclosed area of two Tilez next to an enemy 'Smart Chaser' Grunt (neither can move).

* GunHatz take no damage from a SpongeGun (but are moved) and half damage from any other ranged weapon Gruntz.
** Shieldz take no damage from Bare-handed, (Boxing) Glovez or other Shield Gruntz, and they take half damage from many other Gruntz.
An opponent's 'Hit' value in Yellow indicatez half damage.
An opponent's 'Hit' value of '0' in Red indicatez no damage.
An 'undecided' result is because of random delayz (flailing, etc.) by either opponent.

Grade: A+ 4 W0-D4-L19 (-380 -380) ... NO offense, must be protected at all cost!

The solver, using "hit & run" tacticz, can greatly alter the resultz against most enemy Gruntz.
