There are 8 easter eggs in Leisure Suit Larry 7. They are recognized by the multi-colored egg flashing in the top left or top right of the game screen when active.

At the Clothing Optional Pool, click on the Pesky Branch that's covering Drew's breasts. Select Other and type "Push". Wow, breasts.

In the Library, click on the beaver on top of the right shelf. Select Other and type "Milk". The first time you enter the Jugg's dressing room (next to Johnson's bar at the back deck of the Proud Lil' Seaman Lounge), you will see the Jugg's egg. And not only breasts this time.

After the performance of the Jugg's go on the stage (Proud Lil' Seaman Lounge again) and go to the left. Click on the mixing table, select Other, type "Feel". Now go to Drew Baringmore and talk about "Fokker".  You don't have to look here in the eyes any longer. You will be looking at something else instead. Just guess.

After winning Strip Liar's Dice from Dewmi, return to her cabin and take the bottle of Orgasmic Powder from her table. Make sure you have Drew's suitcase and return to Drew. Talk to Drew. Use the Orgasmic Powder on what's left of her Gigantic Erection drink, click on the drink, select Other and type "Drink". Talk to Drew about her suitcase.  When she leaves, Larry won't block the view anymore. Yeah, yeah, again.

Leave and return to Victorian Principles (the librarian) after putting the The Erotic Adventures of Hercules book in the Prudish and Proud book jacket on her pile of books. Now she's Vicky. Before doing anything else, click on the leftmost guy in the shower on her computer display (it shows the shower from Larry 6), while holding the control-key on your keyboard. Now just play on. Selecting the topic Weather will trigger the second part of the egg. I'm sorry, breasts again.

Go to Captain Queeg's Ballroom, click on Larry, select Other, type Dream and yes, some more breasts.

After killing old Boning, but before giving the Insurance Policy to Annette, return to the Owner's Suite. Click on the bulge of the third guy statue at the left, select Other and type "Unzip". Now push the doorbell. Again, some more breasts and ... money.

The last egg will only show up if you found all Dildo's, scored a maximum 1000 points and found the 7 other eggs. You should look through the credits until the end. Suddenly, just before the alien invasion from outer space, an egg will show up a the top left of the screen. Look quickly at the Captain Thygh egg. It barely lasts two seconds, but you will see some breasts again.
