Answer the following question: Read the following paragraph and extract the answer for the question: Who is it that Tom and Jerry fear has crawled into a cement mixer?  Babysitter Jeannie (voiced by Julie Bennett) is instructed to look after the baby while his mother (also voiced by Julie Bennett) goes out. However, Jeannie pays more attention to talking on the telephone apathetically than her actual babysitting. In the midst of Tom and Jerry's usual fighting, they see the baby crawling out of its pram. Any attempt to return the baby to where it came from simply results in the baby escaping from the pram again. During one escape, the baby crawls into Spike's dog house. Tom accidentally grabs Spike instead of the baby, and is promptly attacked, scratched and bit. This time, Tom angrily brings the baby back to Jeannie herself, who hits Tom over the head with a broom, thinking that Tom has taken the baby away from her. Realising that the baby is no longer worth the trouble, Tom does nothing the next time that it crawls from its pram. However, he and Jerry are forced to react after the baby crawls down to the street and into a 100-story mixed-use skyscraper construction site. The baby crawls from one steel beam to another while the two look on. Jerry manages to catch up, and saves the baby from crawling off a wooden plank lying on the 50th floor by grabbing his diaper. The diaper comes loose, and the baby falls, but he is then caught by Tom. Tom attempts to put the baby's diaper back on, but in the impending confusion, ends up putting the diaper on himself while the baby crawls off, nonchalantly. Tom and Jerry catch up with the baby, only to lose it again, and fearing that it has crawled into a cement mixer on the 30th floor, the two dive straight in, only to find that the baby never did enter the mixer but instead playing with a hammer. The baby then playfully bonks Tom on the head.
Answer:
the baby
