I will post the solutions to some of the main puzzles in this. So if you don't want those spoiled for you, please don't read!
The Hi-jinks are:
Bashful: Hit 10 dolls with the Bindle Bash ability. (The large hobo with the bindle over his shoulder has this ability.)
Ten-Gallon Trawl: Use "Go Fish" ability to yank off 5 doll hats or Helmets. (Small doll with a fishing pole for this)
Bunny Train: Make 5 dolls bounce with Mr. Whiskers at once (you can find the bunny inside a box car near the main area, you need the Raccoon to get him, I'll say how to get the raccoon shortly)
Patchy Behavior: Use "Slap Patch" on 5 dolls. (The small girl doll has this ability)
Pail Faced: Give 5 ghouls bucket helmets (You can find the bucket salesman in the main area)
Raccoonnaissance: Enter all burrows with the raccoon (The raccoon can be found near the raising house, close to the doll Cornelius Caboose, who you need to jump into to get the Raccoon. Use Cornelius' Smoke out ability on the hole in the wall to draw the little guy out)
There are two burrows in the raising house area, and one in the main area that you find the bunny in.
Sir Splitter: Split 10 dolls by jousting them (use the suit of armor for this.)
To get the suit of armor, have one of the dolls with a pallet on his head pick up one of the small dolls. Place this small doll on the stack of pallets by the suit of armor, then unstack till small enough to jump in the smaller toy(may take some doing to get the position correct). Hop down and jump in the armor.
Pan Fried Combo: Hit 7 dolls at the same time with a "Fire Breath" and "Pan Handle" Ability
(You must have beat the game to have access to this.) Grab Pliny Pan-Pounder and Floyd Fire-Breather and take them to the celebration area (This is at least where I got it), use Floyd's fire ability, jump out of him and use Pliny's Pan-pounder.
Smoker Meat: Use the "Smoke Out" Ability on any doll with a meat hat 5 times. (Use Cornelius Caboose for this, he is found by the raising house)
Grab any medium to large sized doll and go to the rotten meat seller in the main area. He will put some mean on that dolls head, jump in Cornelius and use his Smoke Out ability on them.
The Rear Animal: Use the "Unsavory Sniff" on the backside of adult dolls 5 times. (Use Gilliam the Panda for this)
To get Gilliam, first you must have the bunny and the Raccoon(I stated early how to get them.). Once you have them, go find the panda in the main area and do the bunny hop in front of him, he will jump down and you can climb inside him with the raccoon and bunny. A cut scene will play and you will now be able to go around sniffing people with a panda.
