When my son was first born I concocted a diabolical scheme. Noticing that other 2- and 3- year olds had a propensity to bond and constantly carry a cute plush toy, I was determined to freak out other parents by having my son fall in love with a plush squid I bought at the local aquarium. Ultimately, my plan failed because my son never ended up showing an interest in any plush (I had a pile of untouched stuffed critters of all shapes and sizes to prove it), but that doesn't mean that the theory isn't sound and someone else can't disturb the normals in their neighborhood.
To this end, Ron Jon Surf Shop has two plush tikis on clearance in their online store. "Party Hard" is green and "Party Hardy" is orange; both are 9" tall and safe for children 3 and up.
Each is currently priced at a prank-friendly $2.88. Maniacal laugh not included.
