I clutched the steering wheel tightly, maneuvering the bioship carefully without hurting its passengers.
Behind me, Robin was changing into his diving suit. It took every inch of my mere human strength to not look back at him while he was changing.
"This is nice," he ব্যক্ত finally, sitting in the আসন beside me. "We never have time to talk privately."
I smiled as I gave the wheel to him and changed into my diving suit. "Batman's really killing me with the work hours he's giving; could আপনি persuade him to give us a দিন off?"
He looked at me as if that task was impossible. "You're talking about trying to persuade the man who stays in the প্রহরাদানার্থ উচ্চ রক্ষ during Christmas."
We finally landed outside the zoo, and Robin turned the bioship into Invisible mode. It was tricky walking to the polar ভালুক exhibit with giant flippers, but we made it work.
Robin lifted me to the শীর্ষ of the tank, where I slid on my goggles and jumped in the water. The following splash meant that he was close behind me.
I swam gracefully, looking for any secret hatches to where Mr. Freeze would be hiding. Finally, I spotted a large patch of white sitting just a few yards ahead of us. I pointed at it so Robin could see, and we headed towards it in no time.
As we got closer, I noticed that the white spot was moving. If I wasn't going insane, the spot was swimming towards us with big black eyes and large pointy teeth.

It was two of Mr. Freeze's polar bears.
