In my classroom I have a large storage closet

In my classroom I have a large storage closet. More like a small bedroom filled with shelves and boxes. As I was setting up the room a few weeks ago, I put one of those bright orange ‘live animal’ stickers that you can get at the airport on the door. I did not say a thing to the students about what was behind the door but as they allegedly started hearing things, a rumor began to spread. The students all know my interests in unusual animals and began asking what I had behind the door. I told them, “I will show the class when I think all of you are ready”. This loaded statement was interpreted more like, "there are wild animals behind the door that I am taming after school hours."
To backtrack, I ordered four Giant Marine Toads (Bufo Marinus) from Carolina Biological Supply before school began. I was desperately waiting for my secret order to be processed, as now I could not disappoint. When I received the confirmation that the order would be arriving this past Wednesday, I then told the students I would show them what was in the closet, that Wednesday afternoon. Wednesday morning, I received a few packages but none of them contained live animals. In class the students were restless and beging to please just open the door of the closet. I got halfway through class and finally gave in. I told them that their was nothing behind the door other than a bunch of boxe, they still wanted a look. But then I then told them ,"but, there actually would be some animal arriving later in the day’. They were disappointed but continued to be curious about what was going to arrive. I let the students explore the closet as they swore that unusual sounds had been heard ever since the start of school.
Just as they began to look around I received a knock on my door. Opening it up, there was the delivery; with one of the boxes having round holes in the top and live animal stickers on the sides! I prompted all of the students sit back in their seats and brought the new packages inside. While the students sat on the edge of their seats, not knowing what was going to happen next, I got a portable plastic sink out of the closet. The sink, about a foot and a half deep, with two foot long legs, was intended for use around the classroom. I carefully and slowly cut open the package I thought would never come. Inside were the toads; two of them as large as my hand, with fingers extended. I carefully dumped the four creatures in the sink with the moist moss that they came with and tried to prepare myself for whatever reaction was to come. I picked rows students to come up, one row at a time, to view our new animal friends. As the toads hopped around in the sink, the students became increasingly loud and squirmy. As the excitement grew, I could not keep all of the other students seated and many more started to gather. As most of the class looked over each other’s shoulders into the large sink, something amazing happened. One of the larger round stubby legged toad specimens, probably scared to death and thinking it was judgment day, seemingly defied gravity and leapt out of the sink, right down between two students shoes, landing with a ungraceful plop on the hard floor. The class erupted in yells and screams. Everyone began to backpedal to his or her desks. Girls, and boys, were now shrieking. Students jumped onto their chairs and then on top of their desks. At that point I gave up on trying to say anything to calm the class, as the overreaction was totally out of my control, and actually now becoming pretty entertaining. I quickly became more interested in the toad’s safety and as I looked down. The toad hopped into the dark of my closet. I quickly shut the door, put a piece of cardboard over the sink, and began my attempt to settle everyone back down. Within a few minutes the class was all back sitting in their seats, some still out of breathe. I explained to the students that I could find the toad later and tried to provide a little order in a remaining few minutes of class. Later that afternoon, my ears still ringing, all of the other students and teachers in the hall began to ask, “What happened in Science today Mr. Scherrer, is everything okay?” All I could do was smile.
