Now fer my tactics:

Scotty suggested that he go for Mr P while I take on Mr Chrome...seems fair
As STR promply removes Mr Ps tracks, Whirly will concentrate on revving up the spinny shell and attack Mr Chrome from the sides. The armour should hopefully receive some good slices...and maybe, I can try ripping into the fists
If Mr Chrome is still standing after these blows, Ill simply ram the new HB into the wall again and again until ees out for the count
