Tigger is introduced in Chapter II of House at Pooh Corner, when he shows up on Winnie-the-Pooh’s doorstep in the middle of the night, announcing himself with a big bounce. Most of the rest of that chapter is taken up with the characters’ search for a food that Tigger can eat for breakfast – despite Tigger’s claims to like “everything”, it is quickly proven he does not like honey, acorns, thistles, or most of the contents of Kanga’s pantry. In a happy coincidence, however, he discovers what Tiggers really like best is extract of malt, which Kanga has on hand because she gives it to her son, Roo, as “strengthening medicine”.
From that point on, Tigger lives with Kanga and Roo in their house in the northeastern part of the Hundred Acre Wood near the Sandy Pit. He becomes great friends with Roo, and Kanga treats him in much the same way she does her own son. Tigger also interacts enthusiastically with all the other characters – sometimes too enthusiastically for the likes of Rabbit, who sometimes seems exasperated by Tigger’s constant bouncing, Eeyore, who is once bounced into the river by Tigger, and Piglet, who always seems a little nervous about the new, large, bouncy animal in the Forest. Nonetheless, the animals are all shown to be friends.
In addition to chapter II, Tigger also appears in chapters IV, VI, VII, and X of The House at Pooh Corner, and is mentioned in several others. He is the only new major character to be introduced in The House at Pooh Corner; all of the others had been established in the earlier Winnie-the-Pooh book
