Explanation:
GRANDFATHER bought Toto from a tonga - driver for the sum of five rupees . The tonga - driver used to keep the little red monkey tied to a feeding - trough , and the monkey looked so out of place there that Grandfather decided he would add the little fellow to his private zoo . Toto was a pretty monkey . His bright eyes sparkled with mischief beneath deep - set eyebrows , and his teeth , which were a pearly white , were very often displayed in a smile that frightened the life out of elderly Anglo - Indian ladies . But his hands looked dried - up as though they had been pickled in the sun for many years . Yet his fingers were quick and wicked ; and his tail , while adding to his good looks ( Grandfather believed a tail would add to anyone's good looks ) . also served as a third hand . He could use it to hang from a branch : and it was capable of scooping up any delicacy that might be out of reach of his hands . Grandmother always fussed when Grandfather brought home some new bird or animal . So it was decided that Toto's presence should be kept a secret from her until she was in a particularly good mood . Grandfather and I put him away in a little closet opening into my bedroom wall , where he was tied securely -- or so we thought A few hours later , when Grandfather and I came back to release Toto , we found that the walls , which had been covered with some ornamental paper chosen by Grandfather , now stood out as naked brick and plaster . The peg in the wall had been wrenched from its socket , and my school blazer , which had been hanging there , was in shreds . I wondered what Grandmother to a peg fastened into the stened into the wall .
