After leaving the Joker's underground hideout, Ivy lead Harley towards Gotham City's dock area. Another area filled with lots of empty warehouses. Finally Ivy, weaving slightly from near exhaustion, lead Harley to the Happy Exotic Plant Import Company, now defunct.
Pushing open the doors Harley could see the warehouse was nearly bare. The only thing left in the room was piles of fertilizer stacked near a back wall.
Ivy made a beeline straight to the canvas bags and reaching behind them she released a hidden catch. The wall then opened backwards, bags of fertilizer and all to reveal a small room behind.
Ivy entered the room and walked straight over to a large round flower bed in the center and collapsed on it.
Harley after studying the wall and hidden catch figured out how to shut the secret door. A large overhead skylight allowed bright moonlight to flood into the room for her to see by.
Walking over to Ivy, Harley sat down on the edge of the flower bed.
"You can't imagine how many times I dreamed of getting you into my flower bed Harley… And now that I have, I'm too tired to do anything about it." Ivy said with a sigh and promptly fell asleep.
Harley, still energized from Ivy's blood running through her body couldn't rest and wandered around Ivy's hideout. She saw exotic plants growing all over the place. Moss and ivy covered all the walls. She found out that automatic water and fertilizer systems kept the plants living and growing until Poison Ivy could make it back to check on her plants.
"Pity I couldn't have gotten something similar for Bud and Lou." Harley thought sadly to herself. Sitting down at a garden table in the room Harley lowered her head to cry. But after a moment she looked up with a determined look on her face. She might have lost her 'babies' but she wasn't going to lose Ivy to the Joker. And there was only one way Harley could think of to keep Ivy safe. They had to get out of Gotham.
Reaching over she pulled a long piece out of one of the canvas bags that contained fertilizer and searching a bit longer she found a black felt tip pen.
Concentrating for all she worth she began to list out on the canvas material all the electronic parts the Joker had used in his sonic device. She had been with the Joker for every theft and one thing Harley had was an extremely good memory.
Looking at her list one last time Harley added a few more things and then rolled the material into a rough tube. Realizing she left her purse behind, she with a grimace unzipped the top part of her costume and stuffed the list between her breasts and then zipped the costume back up.
"The fertilizer on that canvas really stinks. After this is over I need to have a good shower or bath or Ivy won't want to touch me. Then again, Ivy might consider the smell of fertilizer to be a turn on." Harley thought with a grin.
Pulling another section of canvas off of yet another bag of fertilizer she quickly wrote out a note for Ivy. Placing the make shift note on the bed beside Ivy, Harley then grabbed up two of the black bags filled with the Joker's money and made her way out of the secret entrance and left the warehouse.
Making her way along in the darkness Harley made for the harbor area of Gotham City. Fortunately Ivy's place was fairly close to where she wanted to go so she hoped she could get there and back before Ivy woke up.
