Lucas's foot is ill，which causes his 1 to swell（肿胀） and hurt.As a result，the other penguins at the zoo didn't want to hang out with him.He felt 2 .
The zookeeper decided to do something about it.They had Lucas walk across sand，took notes of his footprints and sent them to an factory called Thera﹣Paw，which creates custom（定制的）products for 3 like penguins that have special needs.
Thera﹣Paw's team created a 4 pair of shoes for Lucas."It can help Lucas fully join the group and behave more typically for a penguin — 5 climbing the rocks and swimming.And the color of the shoes looks very close to his natural foot color，so they don't stand out too much，"said the team.The task was a 6 .Zookeepers put Lucas' new shoes on him and he began trying 7 out at once.
Now he can move around and play 8 other penguins.In fact，it's going even 9 than expected—Lucas already has a girlfriend.
The San Diego Zoo is the largest zoo in California.And it turns out that Lucas isn't the first animal there that has ever needed help in 10 .Earlier this year，a three﹣month﹣old giraffe was finally able to walk and jump on its own with the help of special leg braces.
