[Finding Dory] How the hell are sea urchins allowed in the interactive area (spoilers, maybe)?!

During their escape, Dory and Hank (the octopus) got into a small pool full of animals like starfishes and sea cucumbers. Kids grabbed these animals and some even stabbed their hands trying to grab the sea urchins. Knowing that are urchins are venomous (?), how is there an area where children are allowed to grab echinoderms?

Not all urchins are poisonous, the owners probably thought it was better to teach the kids that some of the animals were dangerous in a controlled environment than to let them find out somewhere where help couldn't reach them in time.
