Arrives at speed, greets everyone, finds the buffet.
Often a Golden Retriever, Beagle or Pug, though every pet is its own animal.
The Party Crasher is a Sock Thief who has discovered catering. All the speed and all the friendliness, pointed at the buffet. The doorbell is the best sound in the world, and the second best is a packet opening.
Does the rounds of every picnic blanket and is welcomed at most of them.
In the kitchen. Always in the kitchen.
Greets every animal like a returning relative.
