Beistle
Jointed Octopus Party Decoration
from $8.09
Under the sea parties tend toward static decor: fish taped to walls, streamers hanging still. A jointed 32-inch octopus helps with that, since the sections move where you pose them; bend an arm around a doorframe or reach one toward the snack table.

Beistle
Whale Hat
from $18.46
Foam whale hat in blue and red, one size fits most.

Beistle

Shark Party Cupcake Stand
from $9.90

Color: blue/gray
Sold by the package (1 cupcake stand) or by the case (12 cupcake stands)
Beistle

Beistle
Shark Headband
from $9.82
Snap-on shark headband with the full anatomy: detailed eyes, teeth, and fins in gray and red, riding on a band that fits most head sizes.

Beistle
Luau Party Tissue Lobster
from $6.16

Beistle
Shark Party Silhouettes
from $7.70
Ten black shark silhouettes ranging from 10 to 15 inches, printed on both sides so they read correctly hung in a window or turning slowly from the ceiling. The mixed sizes fake depth: small sharks look far away, big ones look close, and suddenly the room is underwater.

from $7.70
Fifty-four by 108 inches of plastic tablecover in a classic blue shark pattern, which drapes a standard 6-foot or 8-foot rectangular table with overhang to spare.

Beistle
Luau Party Plastic Crab
from $4.24
Plastic crabs in red with orange print, each 13 by 19 inches. Plastic is the practical choice here: these handle an outdoor table, get wiped down, and pack away for next summer, which is more than tissue decorations can claim. They work on tables, as centerpieces, or as wall accents.

from $8.47
Shark week, but for your ceiling: 12 whirls per package, 6 printed with shark icons and 6 plain, in lengths from 17.5 to 28.5 inches. The mix of lengths is deliberate; alternating them fills the overhead space in layers rather than one straight line, and they spin on ordinary room air.
