Blobby Blob >;3 <3

STORY 2 (I have 2 ideas, tell me which ones the best!)
I was standing in the school hall waiting to get on the bus to home. It was the end of the grade, and I had a card from our teacher.
I opened it up, since everyone else opened theirs up- except my friend.
I read some of it aloud.
'Thanks for being a blobby blob in the grade.' I joked.
My friend laughed.
I laughed too.
THIS BIT IS FAKE:
A small green blob fell out of the bag.
My friend opened her bag, trying to mock everyone looking so shocked. She brought her bag down to the floor.
'Hey little guy! Hop in!' She said, smirking to me.
The small blob opened its eyes and made an adorable noise. But- as soon as everyone said: Awh! The blob ate my friend's bag. She screamed. The blob ate everyones bag, and coat. then closed its eyes when the teacher assistant came back and called everyones names out.
Once she did that, she counted everyone standing. She put her board down and lost attention to what she was doing. She looked at the blob, now medium sized and said: Awh!
But the blob had other ideas. It ate the clipboard and ate the teaching assistant.
Then it became so big it was the size of the school (The school is pretty big...)
The cops were called and they shot bullets at the blob. But when they got to the blob, it just absorbed them.
It still roams, and there are few survivors.
