With a manic grin, Ace snatched a canister from her pack. "One Nitro-9, short fuse!"
"Go on, then," the Doctor urged as he peered around the corner at the giant mantis galloping toward them at top speed.
"Really? You'll let me?"
"Do it, Ace!"
She hurled the cannister. It popped in midair, spraying black liquid everywhere. The insect skidded past on the slick and crashed into the wall, collapsing in a shattered heap.
"Excellent work, Ace!"
"But my Nitro-9!"
"More like WD-40," the Doctor quipped. "Area dispersal valve. Effective and quite a bit safer."
"But no boom," Ace grumped.
"Exactly."
