What do you do with the graham cracker on big nate island?

Answer 1

Go to the "Kids Only" room atop the playground and play "Hangman" (Go To Jail). If you win, Nate will give you some (old and stale) peanut butter crackers. Spitsy the lost dog does like them.

Answer 2

Go to the "Kids Only" room at the top of the playground. Go to the "Kids Only" room atop the playground, along with Nate. Play the "Hangman" game at the "Go To Jail" poster (left side).

Nate will think of a word (it won't be that random) and if you guess it, he'll give you the peanut butter crackers to give to Spitsy.

Answer 3

When you use the peanut butter crackers on the playground, Spitsy the dog will dig a hole to bury them. Eventually you will use them to get the time capsule. But first you have to get the Map, and the talking girls are standing right where you want to dig.

To move the girls requires ringing the school bell (find the clapper, scare the seagull from the tower). To get the map requires you to go to the seal island to the right of the lighthouse (look though the telescope on top of the lighthouse, get the jet ski keys from Cap'n Salty, and race Nate to the island).

Answer 4

at the last part use the map to put the graham cracker on the part where the capsule is buried and the dog will dig there and youre done
