It's interesting how Og mistakes the pteranodon for a giant vampire bat. I'm not sure a caveman would even know what a giant vampire bat is, but okay. It's fun, for the Editor, to try to withhold from the players what they're fighting for as long as possible. For another example, instead of saying a stegosaurus is approaching them, say "the stalking death" is coming for them.
Pteranodons were statted in Supplement II: All-American. Stegosaurs have never been statted for Hideouts & Hoodlums yet. Stegosaurs were 3 ton beasts -- I'd put them at 14 HD, with d10 Hit Dice. Stalking death indeed!
And this should happen in H&H more often than you might think. Requiring Heroes to loot and steal for all their trophy items is harsh and forces them to act out-of-character -- better to hand out trophy items as rewards instead (and not all the time, but sometimes).
Also note that Sibyl seems to have a new magic item -- the Wand of Knocking, that will open any portal...
$14 for two to eat in a fancy restaurant? When preparing the price list for Book I: Men & Supermen, I found a site with scanned menus from lots of 1940s restaurants. I suspect you could still spend a lot at an upscale restaurant in the 1930s, so Mutt & Jeff must have been eating on the lighter side of the menu.
