In case you were wondering, you’re looking at a very contented cephalopod indeed! Keeping octopuses healthy means constant mental stimulation, and besides the puzzles we provide for them, the octopuses can be very curious and will seek out the attention of their staff. 

Tactile enrichment like being petted, or playing tug-o-war, are opportunities the octopuses can seek out at their leisure when their staff are around!
